Scenario of the event dedicated to the celebration of the world day of the sea. World Maritime Day - the most interesting in blogs
September 26 (date for 2013) World Maritime Day is one of the international holidays in the United Nations system. This day has been celebrated since 1978 by decision of the 10th session of the Assembly of the Intergovernmental Maritime Consultative Organization (International Maritime Organization, IMO) on one of the days of the last week of September.
The purpose of World Maritime Day is to draw the attention of the international community to the irreparable damage to the seas and oceans caused by overfishing, water pollution and global warming. The two most important tasks are to improve maritime safety and to prevent pollution of the marine environment, in particular by oil. According to the UN, over the past 100 years, fish species such as tuna, cod, marlin have been caught by 90%. About 21 million barrels of oil are poured into the seas and oceans every year. Synthetic waste dumped into large bodies of water kills one million seabirds and 100,000 marine mammals a year. Due to global warming over the past 100 years, the water level in large reservoirs of the planet has risen by 10-25 centimeters.
The Krasnodar Territory is washed by two completely different seas - the Azov and the Black, each of which is beautiful and unique in its own way.
Black Sea (Bulgarian Cherno More, Ukrainian Chorne Sea Rum. Marea Neagra, Tourist Karadeniz) - the inland sea of the Atlantic Ocean basin. The Bosporus connects with the Sea of Marmara, then, through the Dardanelles - with the Aegean and Mediterranean Seas. The Kerch Strait connects with the Sea of Azov. From the north, the Crimean peninsula cuts deep into the sea. The water boundary between Europe and Asia Minor runs along the surface of the Black Sea.
The area is 422,000 km² (according to other sources - 436,400 km²). The outlines of the Black Sea resemble an oval with the largest axis about 1150 km. The greatest extent of the sea from north to south is 580 A characteristic feature of the Black Sea is the complete (except for a number of anaerobic bacteria) absence of life at depths above 150-200 m due to the saturation of deep water layers with hydrogen sulfide. The greatest depth is 2210 m, the average is 1240 m.
Interesting Facts
- The Black Sea is one of the most famous in the world. But the first, most ancient name turned out to be the most tenacious: Pontos Melas, Kara-Deniz, Mavri Thalassa, Schwarzemeer, Black Sea - all these names in different languages mean the same thing - the Black Sea.
- Hypotheses have repeatedly been put forward in the scientific world that the Black Sea arose about six to eight thousand years ago, when the melting glaciers of the world ocean raised the level of the Mediterranean Sea and allowed it to overcome the natural dam, which was the current Bosphorus. After its breakthrough, the waters rushed into the Black Sea with a force equal to the power of 200 Niagara Falls. This natural disaster is reminiscent of the well-known story of the Flood described in the Old Testament. It is noteworthy that the time of the largest natural disaster on earth practically coincides according to both science and religion.
- Even Herodotus called the Black Sea "by its nature the most amazing." One of its features is that organic life in it exists only in the surface 100-200-meter layer; below, to the very bottom (and the maximum depth of the Black Sea is 2245 m) - a huge motionless mass of water, practically devoid of life, because it is contaminated with hydrogen sulfide.
- The salinity of the water in the Black Sea is much lower than in other seas. If the salinity of the Mediterranean Sea is 37 ppm, then in the upper layers of the Black Sea - only 18 ppm, and in the lower layers a little more - 22 ppm.
- The flora of the Black Sea includes 270 species of multicellular green, brown, red bottom algae (cystoseira, phyllophora, zoster, cladophora, ulva, enteromorph, etc.). The phytoplankton of the Black Sea includes at least six hundred species. Among them are dinoflagellates - armored flagellates (Prorocentrum micans, Ceratium furca, small scripsiella Scrippsiella trochoidea, etc.), dinoflagellates (dinophysis, protoperidinium, alexandrium), various diatoms, etc.
- In winter, the Black Sea does not freeze completely. Only in the northwestern part (near Odessa) does a small area of the sea freeze for a short time. True, in the Byzantine chronicles there are references to the complete freezing of the Black Sea (Pontus) in 401 and in 762 AD.
- During the Crimean earthquake of 1927, high columns of fire were observed in the Black Sea near Sevastopol: it is believed that hydrogen sulfide (mixed with methane) was burning, which rose to the surface of the sea and ignited.
- There are no pronounced ebbs and flows in the Black Sea, and water circulation occurs only in the surface layers, which are saturated with oxygen and suitable for the life of marine life. The water temperature in the surface layers in summer can reach +30 °C, and the average water temperature ranges from +8 °C in winter to + 22 °C in summer. The water temperature in the Black Sea near Anapa in the summer months is: in May - 16-19 degrees, in June 19-22, in July-August 22-25 degrees. In autumn, the water temperature in the sea slowly decreases: in September 23-21, and in October 20-18 degrees. After a hot summer and a warm autumn, the sea cools down even more slowly, sometimes in early November you can swim when the water temperature in the Black Sea remains at around +19...17 degrees.
- According to scientists, in the current century the level of the Black Sea will rise by 1-2 meters. This was announced by Valentina Yanko, professor of the Department of General Marine Geology of the Faculty of Geology and Geography of the Odessa National University, at the 2nd International Conference "The Black Sea-Mediterranean Corridor over the Last 30 Thousand Years: Sea Level Changes and Human Adaptation". Experts note that if nothing changes in the next 50-70 years, all the city beaches of Odessa will go under water.
All about the Sea of Azov!!
In ancient times, the Greeks called the Sea of \u200b\u200bAzov the Meotian swamp - for its shallow water and summer "flowering", and the Slavs in the old days - the Surozh Sea.
The area of the Sea of Azov, without Sivash, is 37,800 square meters. km. Its greatest length, from the Arbat Spit to the mouth of the Don, is 360 km; the width from Temryuk to the Belosarayskaya Spit is 175 km. The greatest depth does not exceed 13.5 m, the average depth is 8 m, the volume is 320 cubic meters. km. . The shallowest sea in the world: the depth does not exceed 13.5 meters
The Sea of Azov is 11 times smaller in area and 1678 times smaller in volume than the Black Sea. Freshened by inflowing rivers, especially the Kuban and the Don, it is one of the freshest seas on the planet and freezes easily.
In summer, the Sea of Azov warms up quickly due to small (up to 14 meters) depths (near the coast - up to + 32 ° С). The average annual water temperature in the Sea of Azov is + 11-12 ° C. With long northeast winds, a lot of Azov water is blown into the Kerch Strait, and the Sea of \u200b\u200bAzov becomes shallow. Winter and autumn storms drive water over a vast area, exposing the bottom. Water fluctuations during this period reach 3-4 meters.
In terms of fish stocks, the Black Sea is much inferior to the Sea of \u200b\u200bAzov, in which low salinity, shallow water, good mixing and warming of water create favorable conditions for the development of plant and animal organisms that serve as good food for sturgeon, herring, bream, pike perch, carp, sprat, sprat.
As you know, water occupies most of the earth's surface. The sea, ocean, river, lake are components of the hydrosphere that differ in size, composition and other characteristics. There are a total of 63 seas in the world. They also include the Aral and Caspian lakes because of their large size.
There are several criteria by which the seas are classified: the degree of separation from the oceans, the temperature of surface waters, salinity, the indentation of the coastline, etc. The largest include the Mediterranean, Coral, Caribbean, Arabian and other seas.
World Maritime Day
At the 10th session of the IMO Assembly, it was decided to establish a World Maritime Day. Since that time, this holiday has been recognized throughout the world as one of the most important dates. Between 1978 and 1980. it was celebrated on March 17th. After 1980, the holiday celebration was moved to the last week of September.
In each state, the government determines the exact date at its discretion. World Maritime Day is an international holiday. In addition to this holiday, there is also World Oceans Day and others dedicated to the water element. All of them are designed to draw the attention of mankind to the problems of the hydrosphere.
Goals and objectives of the holiday
World Maritime Day was established with the aim of solving issues and resolving problems related to shipping, as well as the negative impact of human anthropogenic activities on the ecology of bioresources. Enormous damage to water bodies is caused by industrial enterprises that drain their effluents. Accidents on oil tankers also have a negative impact, as a result of which a huge amount of oil enters the seas, and global warming, due to which the level has risen by 25 cm over the past 100 years, etc.
Giant landfills, formed in separate parts of the world's oceans, are comparable in size to small countries. The sea, ocean and other components of the hydrosphere, as well as other components of the environment, require a rational and careful attitude, as well as protection from harmful effects. Maritime safety, as well as the protection of the aquatic environment, are important issues that require special attention.
Shipping
The theme for World Maritime Day 2016 was "Shipping: Essential for the World". Of the entire number of sectors of the national economy, this one is the most international. This area originated in the distant past. From that time to this day, navigation has been a very important component of the international transport system.
In developed countries, maritime transport serves over 90% of foreign trade. In total, its share in the international turnover of goods is about 62%. Fluctuations in the world economy greatly affect the amount of shipping. The economic crisis entails a decrease in demand for the transit of goods by water transport. And, on the contrary, the rise of the world economy provokes an increase in demand for shipping.
Sailing is considered quite a dangerous activity. Ships at sea are completely given over to the power of the elements. And sometimes she is out of control. The danger is also represented by sea pirates who rob merchant ships. Therefore, there is a need to develop a regulatory framework of requirements that govern all aspects of the shipping industry.
Marine pollution by ships
Sea transport, unfortunately, with all its advantages, is a source of water pollution. It occurs during the operation of ships, as well as as a result of accidents. The first type of pollution is characterized by a small amount, but constancy over time. As a result, chronic poisoning of the entire marine environment is formed.
Accidental releases are less common. However, they are characterized by the release of a large amount of hazardous substances that can cause irreparable damage to nature. Petroleum products pose the greatest danger to the ecosystem. The international organization has adopted a number of normative acts, which, among other tasks, regulate the issues of environmental protection. This is necessary in order for shipping to become more productive and safer year by year.
IMO activities
During its existence, the International Maritime Organization has adopted many standards that ensure maritime safety, as well as the protection of the marine environment from pollution by ships. IMO aims to constantly improve the mechanisms governing technical, legal and other issues in the field of shipping. To this end, the organization adopts codes, protocols, resolutions, conventions, and makes recommendations.
While maritime safety has always been the most important issue, other issues periodically come to the fore. On all issues, the IMO is active in order to most effectively prevent all risks and adverse consequences.
How is the Day of the Sea celebrated?
The last week of September is an important period in the life of those people who linked their fate with the sea. After all, it is on one of these days that it is customary to celebrate their professional holiday. However, not only representatives of this profession can join the celebration, but also all those who love the sea, cannot imagine their life without it. In many states, various exhibitions, conferences, and environmental forums are held on this day. World Maritime Day is an important holiday, the significance of which is recognized all over the world.

It is difficult to find in nature anything more beautiful and majestic than the sea element. Constantly changing, boundless, alluring into the distance, shimmering with different colors, sounding - it attracts and fascinates, it is gratifying to contemplate it. The image of the sea was sung by poets, the sea was painted by artists, the melodies and rhythms of its waves formed the musical lines of the works of many composers.
The sea fascinates, the sea kills, excites, frightens, and also makes laugh, sometimes disappears, on occasion it disguises itself as a lake or piles up storms, devours ships, bestows riches, does not give answers; it is wise, and gentle, and strong, and unpredictable. But most importantly, the sea is calling.

World Maritime Day(Eng. World Maritime Day, Spanish Dia Maritimo Mundial, French Journee mondiale de la mer) was established at the 10th session of the Assembly by the International Maritime Organization (IMO), has been celebrated since 1978. Included in the system of world and international days of the UN.
World Maritime Day is dedicated to the problems of environmental safety of maritime transport, the conservation of bioresources. Until 1980, it was celebrated on March 17, but then it began to be celebrated on one of the days of the last week of September. In each country, the government itself determines a specific date.
The holiday is celebrated not only by those who have connected their lives with the sea - employees of the civil and military fleet, but also by everyone who loves the sea.
Marinologists (marine biologists) and oceanologists from all over the world are celebrating their successes in protecting and developing some of the most important treasures of the Earth. Russian specialists are also involved in this, since Russia has a huge research area - in the Pacific and Arctic Oceans, in the Baltic and Black Seas.
Poems and congratulations on world maritime day will be pleased to receive your friends and acquaintances. Send them poems and congratulations on this holiday on Sea Day.
Congratulations on the Day of the Sea in verse
The sea has many different faces:
Storms and calms in the neighborhood.
It knows no boundaries
He is no stranger to hypocrisy.
Under the thickness of heavy waters.
A lot of mysteries are hidden.

World Maritime Day
Prepared by: Efremova V.A.
Teacher: Today, on a beautiful autumn day, I would like to talk about something that reminds us of summer.
"Morning. The sun had not yet risen, only an orange halo appeared from behind the mountains. The water "steams" with a light iodine mist. The sea is as calm as ever. Smooth, like a greenish glass surface. It seems that right from the pebbles you can step on this surface, and it will hold. But no, I feel water on my body higher and higher.
And now I’m swimming, slightly pushing the water apart with my hands, inhaling the fertile fumes. The water is clear, silvery, you can see the stones covered with algae. I sail away and turn around to look at the mountains in all their glory. It seems that they are advancing on the sea. And it backs away, taking me with it. I am lying on my back… To call it bliss is to say nothing. And then, finally, the sleepy sun slowly creeps out, spills smiling, filling the whole space with itself. Blind…”
Grace Spring
As you already understood, today's event is dedicated to the celebration of World Maritime Day. It is celebrated in the last full week of September. This holiday was established1978 by the 10th session of the Assembly of the Intergovernmental Maritime Consultative Organization. The Day of the Sea is intended to remind of the danger that threatens the internal and external seas, emanating mainly from people.
Presenter 1: We congratulate the whole world now,After all, today is World Day of the Sea.Let calm prevail on the sea.Happiness to all, love, kindness, health!
Host 2: Sea! You beckon with your beauty.Foamy waves your rustle is endless.You are the meaning of life for a sailor.Who is in love with you is your slave forever!
Presenter 3: There are many different faces by the sea:Storms and calms in the neighborhood ...It knows no boundariesHe is no stranger to hypocrisy.Under the thickness of heavy watersThere are many mysteries hidden...Happy sea day to all who live in it!To whom did it become the universe!
Teacher: The planet on which we live can more rightly be called "planet-ocean" than "planet-earth". After all, the area of \u200b\u200bthe World Ocean is more than 2 times the area of \u200b\u200bthe entire land. If all the continents were covered with water from the World Ocean, then a layer 9km! There are 1370 million tons of water in the oceans.km 3 water!
The term "World Ocean" was introduced by the prominent Soviet geographer and oceanographer Yu. M. Shokalsky. By this name, he meant "the totality of that water shell of the globe, the main feature of which is salinity."
Sea- part , isolated or the heights of the underwater . It also differs from the World Ocean in its hydrological, meteorological and climatic regime, which is associated with their marginal position relative to the oceans and the slowdown in water exchange due to the limited connection with the open part.
At present, it is customary to divide the World Ocean into 4 separate oceans and 75 seas, including large bays and straits.
What do you think is the importance of the seas in nature and human life?
(student answers)
Presenter 1: The seas play a decisive role in the conservation of the environment, influence the climate of the globe and ensure the balance of the world's hydrological system;
Presenter 2: The seas are the main supplier of oxygen produced by phytoplankton;
Presenter 3: If the seas did not have the ability to retain heat, most of the Earth would be uninhabited;
Presenter 1:The sea is the arena of labor activity for millions of people. In order to equip one sailor or fisherman to sail, 20 people work on land and in ports: at shipyards, net knitting and rope factories and other enterprises. More than 100 million people, residents of the coasts, are somehow connected with the sea.
Presenter 2: Since ancient times, oceans and seas have been a road connecting different countries. And today, maritime transport plays a huge role in the economic and cultural life of peoples. More than 65% of the world's transport cargo turnover is accounted for by the marine fleet.
Presenter 3: Sea water is an inexhaustible repository of a variety of chemical mineral raw materials. All the chemical elements of the periodic system of Mendeleev are dissolved in it, even gold and radioactive elements. Water is an excellent solvent. On average, 35 kg of various salts are dissolved in 1 ton of sea water, but so far there are relatively few of them. This is the business of the future.
Presenter 4:The ocean contains huge stocks of fish, edible shellfish, crustaceans and algae. The total world catch is 45 million tons per year (according to UN data). Of these, only 10% is mined in fresh waters, the rest - in the seas and oceans. First place in the fishery is occupied by fish - 85%, then whales - 6%, mollusks and crustaceans - 8% and algae - 1%.
Presenter 5: The seas are fraught with huge reserves of energy. As you know, under the influence of the forces of attraction coming from the Sun and the Moon, sea tides arise on Earth. Water comes to the shore twice or once a day, often flooding vast areas. The water level in some places rises by several meters. Such a regular movement of water is fraught with huge reserves of energy. Now this energy of the ocean is gradually beginning to be used.
Presenter 6:Every year 448 thousand tons of water evaporate from the surface of the oceans.km 3 water. Of these, 107 thousandkm 3 falls over dry land. So the ocean moistens the lands far from its shores. Watered with it, the earth turns green, bread ripens in the fields, vegetables in vegetable gardens, fruits in gardens. And no matter how far from the seashore the place where we live is, everywhere we receive the gifts of the ocean. They lie on the shelves of stores in the form of packages of salt, barrels of fish, neat cans of canned food and many other products. You walk down the street and admire the cladding of houses: white limestone slabs. The "homeland" of limestone is the deep sea. An airplane is flying high in the sky. The metal alloy from which it is built includes magnesium extracted from sea water. Everywhere there are particles of the great oceans.
Presenter 7:Man already uses many of its riches, but they do not make up even a thousandth of what can be extracted from its depths. The time will come when man, armed with perfect technology, will master all the riches of the underwater world.
Teacher: You listened to the messages of your senior comrades about the significance of the seas in nature. And now we want to test your knowledge. I suggest you take part in a quiz and solve riddles:
For her, the wave is a swing,
And she swims aimlessly
Nowhere to nowhere
Everything is transparent like water. (Jellyfish)
Deep at the bottom she
As if visible in the sky.
But it does not shine and does not warm,
Because he can't. (Starfish)
What an amazing horse.
Very strange habits
The horse does not sow and does not plow
Dancing with fish underwater.
Call him friend
Fish friend ... (Seahorse)
Like a huge ship
He swims in the ocean
No pipe and no screw,
On his back is a fountain. (Whale)
The blue sea is beautiful.
Only swimming in it is dangerous!
No matter how you are "grabbed"
Bloodthirsty ... (Shark)
I'm not a centipede at all!
Where can I get so many boots for the legs?
Eight is enough for me! So a little...
Answer who am I? ... (Octopus)
Fleeing the strong from enemies,
Head back,
I disguise myself in ink
A tattered robe. (Cuttlefish)
This beast is fanged
Instead of legs - flippers,
Tail dragging on ice
The beast is not afraid of frost. (Walrus)
He was friendly with the sailors,
What is still famous.
From sea animals to the same. (Dolphin)
What kind of animals are they anyway?
Among dolphins and whales
Really similar-resembling
On bushes of dense flowers. (Anemones)
Far to the south
Where only ice, frost and blizzards,
Without taking off the black tailcoat,
A fisherman jumps into the sea. (Penguin)
I am famous in the Black Sea
The fact that I walk near the bottom
And poisonous with you
I carry a bone dagger. (Scat)
Near the rocks under the wet wind,
Who, tell me, from the animals
On their sandy beaches
Sunbathing by the seas? (Seal)
Lives in the depths of the sea
Swims quickly underwater.
She has a lot of needles
Like hedgehogs and Christmas trees. (Fish Hedgehog)
We have one employee -
A master carpenter of all trades.
Though he drank it in the water -
Never rust! (Sawfish)
He wears stripes on his back.
Is it a zebra? - someone will ask.
No, she swims in the water
She carries fins. (Striped fish, Clown fish)
A spider crawls into the sea -
Eight legs, a pair of arms.
In the hands of claws
In the eyes - fear. (Crab)
She is well known to everyone.
She is always and everywhere at home.
There is no home for her relatives -
The house is always with her.
With such protection, there is no fear.
Who is this fortress? (Turtle)
Sitting on the rocks, moving his mustache,
And walk will go backwards. (Crayfish)
Lived in rivers and seas,
He is long, but not a snake. (Acne)
It will be scary if hunger
Will overcome the fish - ... (Hammerfish)
Kingdom of fish, whales, squids,
Sea stars, jellyfish, corals. (Sea)
In calm weather
We are nowhere
How the wind blows
We run on water. (Waves)
Storm on the sea or mist
But where is the edge of the earth
Every captain knows.
What burns for them in the distance? (Lighthouse)
I'm sailing on a ship
Sometimes I lie at the bottom
I keep the ship on a chain,
I watch the ship at sea,
To keep the wind from blowing
I just rode on the waves. (Anchor)
On the sea goes, goes
And it will reach the shore, and then it will disappear. (Wave on the sea)
Water to the right, water to the left
Vessels are sailing here and there and here
But if you want to get drunk, my friend,
Every sip will be salty. (Sea)
Breaking thick ice
He goes forward alone
And after him only then
The ships are moving in single file. (Icebreaker)
Bela cotton wool is floating somewhere. (Foam on the sea)
He is the king of the expanses of the sea,
the sovereign of the oceans,
Treasures he is at the bottom of the keeper
And the master of mermaids. (Neptune)
Who puts on a spacesuit
And diving deep?
Who in shoes with lead
Walks there on the bottom on foot? (Diver)
I need a thread for fishing.
I wanted to ask the seller
Like, is it for sale here,
Yes, I forgot what the thread is called.
My nose sweated to a shine.
I remembered! This is ... (Fishing line)
Neptune, obviously, with someone in a quarrel,
If the sea is raging like that!
Waves of all shapes...
What about the sea? At sea… (Storm)
We are timid sometimes
We can be brave too.
Water surrounds us
In it we breathe with gills.
With scales and fins
Swimming here and there
And we walk in shoals
We are on rivers and seas. (Fish)
A wave is rising
And close the shore soon.
This is our moon satellite
This is how the sea attracts. (tide)

Presenter 1. Our country - Russia - is a maritime state. Its shores are washed by the waters of three oceans and 12 seas.
Presenter 2: The total length of the coastline of the seas is 60,985 km;
Presenter 3: The total area of the water area under the jurisdiction of Russia is 8.6 million square kilometers;
Presenter 4: The seas that make up the Atlantic Ocean - the Baltic, Black, Azov, Caspian;
Presenter 5: The seas that make up the Arctic Ocean - the Barents, White, Kara, Laptev Sea, East Siberian, Chukchi;
Presenter 6: The seas that make up the Pacific Ocean - the Bering Sea, the Sea of Okhotsk, the Sea of \u200b\u200bJapan.
Teacher: The Sea of \u200b\u200bAzov is the shallowest in the world, its depth does not exceed 13.5 m
A feature of the Baltic Sea is the abundance of fresh water. The Barents Sea is of great importance for transport and fishing. The White Sea is one of the smallest among the seas of Russia. The Bering Sea is named after the explorer Vitus Bering, under whose leadership it was explored in 1725-1743. The East Siberian Sea is covered with ice for almost the entire year. One of the coldest seas. The temperature even in summer rarely rises above 0 degrees. The largest drainless lake on Earth, called the sea due to the fact that its bed is composed of oceanic-type earth's crust. The Laptev Sea is named after the polar explorers cousins Dmitry and Khariton Laptev. The Black Sea is one of the largest resorts in Eurasia. The International Date Line passes through the waters of the Chukchi Sea. The Sea of Okhotsk is a source of very valuable resources. And not only fish. Quite large deposits of oil and gas have already been explored on its shelf. The Sea of Japan is in first place in the Russian Federation in terms of a variety of fish and a variety of species.
The biological diversity of the seas surrounding Russia is maximum in the south of the Pacific basin and gradually decreases to the north. The Black Sea with its deep hydrogen sulfide horizon is characterized by minimal biological diversity.
The inhabitants of the sea - several hundred varieties of animals, plants and unicellular organisms, whose existence is inextricably linked with the sea element. The open sea is a place where dolphins frolic and sea turtles find their way without a compass. Going down under the water, you can find microscopically small unicellular algae, clouds of tiny crustaceans, schools of fish and squid, as well as a whole complex of sea inhabitants living in the surface layers of water.
Now we will present to your attention the ten most unusual inhabitants of the seas.
Narrator 7: Dumbo Octopus - This animal got its name from the ear-like formations protruding from the top of its head, which resemble the ears of the Disney elephant Dumbo. These cute creatures live at depths of 3,000 to 4,000 meters and are among the rarest octopuses. The largest individuals of this genus were 1.8 meters long and weighed about 6 kg. Most of the time, these octopuses swim above the seabed in search of food - polychaete worms and various crustaceans. By the way, unlike other octopuses, these swallow their prey whole.
Presenter 1: Short-nosed bat - this fish attracts attention, first of all, with its unusual appearance, namely, bright red lips on the front of the body. As previously thought, they are necessary to attract marine life, which feeds on the bat. However, it was soon found out that this function is performed by a small formation on the head of the fish, called an eska. It emits a specific smell that attracts worms, crustaceans and small fish. The unusual "image" of the bat complements the no less amazing way of its movement in the water. Being a poor swimmer, he walks along the bottom on his pectoral fins. The short-nosed bat is a deep-sea fish, and lives in waters near.
Presenter 2: Branchy brittle stars -These deep sea animals have many branched rays. Moreover, each of the rays can be 4-5 times larger than the body of these brittle stars. With the help of them, the animal catches zooplankton and other food. Like other echinoderms, branched brittle stars have no blood, and gas exchange is carried out using a special water-vascular system. Usually branched brittle stars weigh about 5 kg, their rays can reach 70 cm in length.
Presenter 3: Harlequin Pipefish - This is one of the most poorly studied species that can, if necessary, merge with the bottom or imitate a twig of algae. It is near the thickets of the underwater forest at a depth of 2 to 12 meters that these creatures try to stay so that in a dangerous situation they can acquire the color of the ground or the nearest plant. In the “calm” time for harlequins, they slowly swim upside down in search of food. Looking at a photo of the harlequin pipe-nosed, it is easy to guess that they are related to seahorses and needles. However, they differ markedly in appearance: for example, the harlequin has longer fins. By the way, this form of fins helps the ghost fish to bear offspring. With the help of elongated pelvic fins, covered on the inside with filamentous outgrowths, the female harlequin forms a special bag in which she bears eggs.
Narrator 4: Yeti Crab - In 2005, an expedition exploring the Pacific Ocean discovered extremely unusual crabs that were covered in "fur" at a depth of 2,400 meters. Because of this feature (as well as coloration), they were called "yeti crabs". However, it was not fur in the truest sense of the word, but long feathery bristles covering the chest and limbs of crustaceans. According to scientists, many filamentous bacteria live in the bristles. These bacteria purify water from toxic substances emitted by hydrothermal springs, next to which "yeti crabs" live. And there is also an assumption that these same bacteria serve as food for crabs.
Narrator 5: Lyra Sponge - It is a species of carnivorous deep-sea sponge, and was first discovered off the California coast at a depth of 3300-3500 meters in 2012. The sponge lyre gets its name from its harp or lyre-like appearance. So, this animal is kept on the seabed with the help of rhizoids, root-like formations. From their upper part stretches from 1 to 6 horizontal stolons, and on them vertical "branches" with spatulate structures at the end are located at an equal distance from each other.
Presenter 6: Clownfish - Found in almost all tropical and subtropical seas and oceans, clownfish are one of the fastest predators on the planet. After all, they are able to catch prey in less than a second! So, having seen a potential victim, the "clown" will track it down, remaining motionless. Of course, the prey will not notice it, because the fish of this family usually resemble a plant or a harmless animal with their appearance. In some cases, when the prey comes closer, the predator will begin to move the esca, an outgrowth of the anterior dorsal fin that resembles a "fishing pole", which causes the prey to get even closer. And once a fish or other marine animal gets close enough to the clown, it will suddenly open its mouth and swallow the prey in just 6 milliseconds! Such an attack is so lightning fast that it cannot be seen without slow motion. By the way, the volume of the oral cavity of the fish while catching the victim often increases 12 times.
Narrator 7: Mantis shrimp - Living at shallow depths in tropical and subtropical seas, mantis shrimp have the most complex eyes in the world. If a person can distinguish 3 primary colors, then the mantis shrimp - 12. Also, these animals perceive ultraviolet and infrared light. Such eyes enable mantis shrimp to recognize different types corals, their prey and predators. In addition, during the hunt, it is important for cancer to deliver accurate blows with its pointed grasping legs, which is also helped by its eyes. By the way, sharp, serrated segments on grasping legs also help mantis shrimp to cope with a prey or predator, which can be much larger in size. So, during the attack, the mantis shrimp makes several quick kicks with its legs, which causes serious damage to the victim or kills her.
Narrator 1: Anglerfish, Monkfish, Anglerfish - This deep-sea monster can easily become any diver's nightmare and is rightfully considered the ugliest fish on planet Earth. As if ashamed of their ugliness, anglers live in the depths of the sea, where the sun's rays do not penetrate. The depths at which these creatures live are truly amazing: in 2006, a female monkfish was discovered in the Mediterranean Ocean at a depth of 1.86 km. Fishing fish spend most of their lives at the very bottom, where they burrow into silt or sand. Due to their deep-sea habitation, the skin of these fish has a dark gray or dark brown color, which would make them inconspicuous if it were not for a huge flat head dotted with spikes and a giant mouth opening. The palate and jaws have several rows of razor-sharp, inward-curving teeth. Some anglerfish can reach 2 meters in length and weigh up to 28 kilograms.
Presenter 2: Drop fish - This fish is somewhat reminiscent of a person with an unhappy expression on his face, upset by his ugliness. It lives mainly off the coast of Tasmania at a depth of 800 meters and feeds on mollusks and sea urchins. The fish-drop does not have an air bubble, and the body consists of a jelly-like substance, slightly denser than water, which allows it to easily move along the seabed.
Teacher: Despite the fact that water occupies 70% of the surface of our planet, the seas and oceans remain a mystery to humans. No more than 5% of the world's oceans have been explored, the rest of it is beyond the knowledge of people. But everyone knows how rash human activity and his mistakes affect the sea and its inhabitants. And sometimes, these mistakes are costly.
The seas and oceans, their numerous inhabitants are in danger due to the fault of man, who pollutes the waters with toxic substances, plastic waste, oil products. In addition, the problem of poaching and uncontrolled fishing is very acute. Many species of marine animals have already disappeared due to the fault of man, and even more are under the threat of extinction. According to the UN, over the past 100 years, fish species such as tuna, cod, marlin have been caught by 90%. About 21 million barrels of oil are poured into the seas and oceans every year. Synthetic waste dumped into large bodies of water kills one million seabirds and 100,000 marine mammals a year.
We must remember that man is only a part of nature. Destroying the environment on which we depend, we lead ourselves to death.
Let's save our planet!
