The most amazing inhabitants of the world's oceans presentation. Presentation on the theme "Pacific Ocean"

Chudinovskikh Yulia, Buran Anna

What animals live at the bottom of the ocean? This question has always interested people since ancient times. Particularly interesting are the mysteries of the deep-sea world, where creatures that look more like scary monsters live. But this does not stop scientists; researchers are still trying to unravel the secrets hiding in the depths of the water...

The ocean covers more than 70% of the earth's surface and provides about half of the air we breathe through microscopic phytoplankton. Today, about 95% of the ocean and 99% of the ocean floor remain unexplored.

Let's take a closer look at representatives of deep-sea fish, the main difference of which is their unique structure and appearance.

Inhabitants of the world's oceans. Deep-sea world The work was prepared by a student of the 7th FM class Yulia Chudinovskikh, Anna Buran FOR AN OPEN GEOGRAPHY LESSON “The Ocean as a Living Environment” 7th grade, teacher E.Yu. Korosteleva Tolyatti 2015 - 2016

Who lives at the bottom of the ocean? What animals live at the bottom of the ocean? This question has always interested people since ancient times. Particularly interesting are the mysteries of the deep-sea world, where creatures that look more like scary monsters live. But this does not stop scientists; researchers are still trying to unravel the mysteries hiding in the depths of the water... The ocean covers more than 70% of the entire earth's surface and provides about half of the air we breathe thanks to microscopic phytoplankton. Today, about 95% of the ocean and 99% of the ocean floor remain unexplored. Let's take a closer look at representatives of deep-sea fish, the main difference of which is their unique structure and appearance.

Macropinna microstoma Macropinna microstoma belongs to a group of deep-sea fish whose unique anatomical structure has evolved to suit its lifestyle. These fish are extremely fragile, and specimens of the fish that have been caught by fishermen and researchers have become deformed due to pressure changes. The most unique characteristic of this fish is its soft, transparent head and barrel-shaped eyes. Typically fixed in an upward direction with green "lens covers" to filter sunlight, the eyes of the Smallmouth Macropinna can rotate and extend.

Bathysaurus Bathysaurus ferox sounds like a dinosaur, which, in principle, is not far from the truth. Bathisaurus belongs to the deep-sea lizard-headed species that live in tropical and subtropical seas at a depth of about 600 - 3,500 m. The body length reaches up to 65 cm. It is considered the deepest-living predator in the world. Everything that comes in its way is immediately devoured. Despite its sharp teeth, the Bathysaurus's tongue is lined with razor-sharp fangs. Its peculiarity is that it has both male and female genital organs.

Viper fish Viper fish is one of the most unusual deep-sea fish. Known as the common chauliodus (Chauliodus sloani), it is one of the ocean's most ruthless predators. This fish is easily recognized by its large mouth and sharp fang-like teeth. In fact, these fangs are so large that they do not fit in her mouth, curling closer to her eyes. The viper fish uses its sharp teeth to pierce its prey by swimming towards it at very high speed. Most of these creatures have a stretchable stomach, which allows them to swallow fish larger than themselves in one sitting. At the end of its spine is a luminous organ that the fish uses to attract its prey. It lives in tropical and temperate waters in different parts of the world at a depth of 2,800 m.

Monkfish The Deep Sea Anglerfish looks like a creature from a science fiction world. It may be one of the ugliest animals on our planet and lives in the most inhospitable environment - the lonely, dark seabed. There are more than 200 species of monkfish, most of which live in the murky depths of the Atlantic and Antarctic oceans. The monkfish lures its prey with its elongated dorsal spine, curving it around the bait, while the end of the spine glows to attract unsuspecting fish to its mouth and sharp teeth. Their mouth is so large and their body so flexible that they can swallow prey twice their size.

Piglet squid (Helicocranchia Pfefferi) is a species of squid that lives about 100 m below the ocean surface. Due to its habitat in the deep ocean, its behavior has not been well studied. These inhabitants are not the fastest swimmers. Their body is almost completely transparent, with the exception of some cells containing pigments called chromatophores, which give these inhabitants such a charming appearance. They are also known for their glowing organs called photophores, which are located under each eye. Piglet squid

This fish lives off the coast of Australia and Tasmania at a depth of about 800 m. Given the depth of water in which it swims, the blob fish does not have a swim bladder like most fish, as it is not very effective under high water pressure. Her skin is made of a gelatinous mass that is slightly denser than water, which allows her to float above the ocean floor without any hassle. The fish grows up to 30 cm in length, feeding mainly on sea urchins and shellfish that swim by. Even though this fish is inedible, it is often caught along with other prey such as lobsters and crabs, putting it at risk of extinction. A distinctive external characteristic of the drop fish is its unhappy facial expression. Blob fish

World ocean

The flora and fauna of the ocean is rich and diverse. Currently, about 160 thousand species of animals and more than 10 thousand species of algae have been discovered in the ocean.

• Most of the ocean (almost 5%) has a complex topography, and its depth is over 4000 m.

• The deepest place on Earth is the Mariana Trench (11,034 m).

Distribution of living organisms

• Living organisms are distributed everywhere, but unevenly
• The species difference depends on:

- latitude of the place

-from depth

-from the distance from the coast

- on salinity and density of waters

Deep layers

• Poor lighting
• High blood pressure
• Low temperatures

Surface layers

• Good lighting
• Oxygen saturation
• Warmer zone

The living conditions of organisms are very favorable

1. There is a buoyant force of water, so large organisms can live in it.

• 2. There are no sharp changes in water temperature between seasons.
• 3. Oxygen is dissolved in water, marine organisms breathe.

Vegetation in the ocean

• Aquatic plants - algae. Distributed to a depth of 200-250 m.

• Divided into attached and free-floating
• Absorb oxygen across the entire surface

seaweed

Seaweeds are ancient plants that live primarily in water. Here we encounter both unicellular and multicellular organisms, as well as large forms of various structures.

seaweed

• Even in color, seaweeds are not the same, since some contain only chlorophyll, others also have a number of additional pigments that color them in different colors.

Flora of the seas and oceans

• The flora of the ocean and seas is as rich and diverse as the flora of land. Most of the biomass comes from the Pacific Ocean (about 50%).

• These are unicellular and red algae.

Wolfia rootless is the smallest plant in the world.

• Fucus plants, among which there are sea oaks.

The main feature is many pairs of air bubbles that help the plant maintain a vertical position in the water.

• sea ​​grapes

algae king

And the coasts of the Pacific Ocean

• are famous for their magnificent mangroves that can grow in salt water.

• kelp

sargassum

• In the northern part of the Indian Ocean, closer to the equator, there are amazing dinophyte algae that can glow at night.

Dinophyte glow of algae

• About 240 species of phytoplankton and the hardiest algae live there. There are only 18 types:

diatoms, distomea, red algae, kelp, fucus, sea anemones, sea lilies, and others.

Presentation “Inhabitants of the seas and oceans”

Slide 1. « Inhabitants of the seas and oceans»

Slide 2. Sea inhabitants

Slide 3. Dolphin. Dolphins live in all open seas and sometimes enter the mouths of large rivers. Representatives of the family of freshwater, or river, dolphins have a much more limited distribution. For the most part they inhabit inland fresh water bodies, although some of them can even penetrate coastal areas seas.

Slide 4. Sea turtles are excellent swimmers and divers. These large reptiles, clumsy on land, glide gracefully through the water with the help of flipper-like forelimbs and streamlined carapace. When sea turtles are active, they often come to the surface to breathe. And during rest, some species can remain under water for several hours.

Slide 5. Starfish Starfish got their name due to their original form (rays)

Slide 6. Starfish got their name due to their original form: they have from 5 to 40 limbs (rays). These animals are predators. The stars feed on mollusks and various bottom invertebrates.

Slide 7. Whales are the largest among animals. In adulthood, they reach an average body length of 25 m (the largest is 33 m, and their weight is 90-120 tons.

Slide 8. Sea urchin. These representatives of marine fauna live on the bottom. They move with the help of special legs. The legs are long elastic processes. They have suction cups at the ends, so the marine life can crawl not only on horizontal, but also on vertical surfaces.

Slide 9. Seahorses live in tropical and subtropical seas. They lead a sedentary lifestyle, attaching their flexible tails to plant stems and changing body color, completely blending into the background. This is how they protect themselves from predators and camouflage themselves while hunting for food. Skates feed on small crustaceans and shrimp.

Slide 10. Octopuses are the most intelligent among all invertebrate animals. Octopuses are often colored brown, red, or yellowish, but they can change color no worse than chameleons.

Slide 11. Sharks live in waters all over the world ocean, that is, in all seas and oceans. Some species of sharks are able to live in both salt and fresh water, swimming into rivers. The depth of habitat of sharks is on average 2000 meters, in rare cases they descend to 3000 meters.

Slide 12. Crabs inhabit all seas and oceans of the planet. Along with a special body shape, crabs are characterized by the presence of 10 pairs of limbs.

Sly 13. Stingrays live in all seas and oceans and live both in the cold waters of the Arctic and Antarctic, and in the tropics. Stingrays have organs that produce electricity.

Slide 14. Jellyfish. These amazing animals live only in salt water, and therefore they can be found in all oceans and seas of our. Among the representatives of this class there are both heat-loving animals and those that prefer cold waters, species that live only near the surface of the water, and those that live only at the bottom ocean

Planet Ocean Land divides a huge expanse of water into four parts - these are the oceans. The World Ocean covers 2/3 of the globe, contains 97% of all water on earth. The largest of them is the Pacific Ocean, and there is also the Atlantic, Indian, and Arctic Oceans

Inhabitants of the Planet Ocean Life in the ocean is incredibly diverse: it is home to species of organisms from microscopic single-celled algae and tiny animals to whales exceeding 30 meters in length

Marine fish amaze with the diversity of their species: there are many exotic fish, but they do not form the basis of its biological balance.

Atlantic Ocean The Atlantic Ocean is second in size only to the Pacific Ocean; its area is approximately 91.56 million km2. It is distinguished from other oceans by its highly rugged coastline, forming numerous seas and bays, especially in the northern part.

Giant Rayfish The massive one-kilogram black rayfish known as "Zeus" has a diameter of 4 meters, including a 1-meter mouth. The massive one-kilogram black rayfish is known as "Zeus" and has a diameter of 4 meters, including a 1-meter mouth.

Hosts of the Ocean The Indian Ocean shelters many animals dangerous to humans. The ocean has a large number of poisonous sea snakes, there are even saltwater crocodiles. Among the birds, frigates and albatrosses can be called hosts. Penguins live in the cold southern waters

Arctic Ocean About 40 million years ago there was a giant lake. The Arctic Ocean is the smallest ocean on Earth by area, located between Eurasia and North America. Eurasia North America Area 14.75 million square meters. km, average depth 1225 m, greatest depth 5527 m in the Greenland Sea. Water volume 18.07 million km³. Greenland Sea

Narwhal Narwhal lives in the latitudes of the Arctic Ocean. Body length is m. The weight of males reaches 1.5 tons. The only tooth in males has grown in length and turned into a tusk

The polar bear is one of the largest land mammals and the largest predatory animal on the planet. The weight reaches kg, and sometimes even a ton. Under natural conditions, it lives for about 19 years. The polar bear is one of the largest land mammals and the largest predatory animal on the planet.
