The Pacific Ocean is the largest ocean in the world and covers about a third of the Earth's surface area. The depth of the ocean varies from shallow shores to the Mariana Trench, the deepest point of which (Challenger Deep) reaches a depth of almost 11 thousand km. Due to its sheer size, the Pacific Ocean is home to countless species of sea creatures, and some of the most famous animals are:
Penguins
The Pacific Ocean is home to numerous species, including Galapagos penguins, Humboldt penguins, Magellanic penguins, crested penguins, and yellow-eyed penguins. These animals vary in size, from 1 kg in weight and a height at the withers of about 40 cm, to a weight of 35 kg and a height of about 100 cm.
Dugong
Elephant seals
The largest genus distributed in the Pacific Ocean. It includes two species: the northern elephant seal and the southern elephant seal. The northern species is distributed in the northern part of the Pacific Ocean along the North American coast, and the southern one is found near. These enormous marine mammals exhibit sexual dimorphism, with adult males being much larger than females. The average weight of an adult elephant seal is about 2 tons, with some individuals growing up to 4 tons.
Manti
The largest stingrays live in the northern part of the Pacific Ocean - representatives of the Manta genus. They are found near coral reefs, where they hunt fish and tiny fish. Adult manta rays can have a body width of up to 9 m and a weight of 3 tons. The stingray is a solitary animal and surprisingly calm, despite its impressive size. Stingrays are hunted by large sharks and killer whales.
Sea otters
The sea otter is a common inhabitant of the North Pacific Ocean, especially on its northern and eastern coasts. Sea otters are relatively small in size compared to other marine mammals, and adults can reach a maximum weight of about 45 kg and a body length of up to 1.5 m. They feed on small marine animals and seaweed.
sea turtles
Sea turtles are a general term used to describe seven species in the order turtles. These species include: flathead sea turtle, green turtle, hawksbill turtle, Atlantic ridley turtle, leatherback turtle, loggerhead turtle and olive turtle. The leatherback turtle is the largest of all sea turtles, with adults weighing up to 700 kg. Sea turtles are found in tropical areas of the Pacific Ocean.
Sea slugs
Sea slugs are the term used to refer to marine species known as nudibranchs, as well as several gastropods that closely resemble terrestrial slugs. Sea slugs are primarily found in coral reefs and come in a variety of shapes and sizes, but most are partially translucent. Most sea slugs have feather-like structures on their backs that act as gills. Sea slugs are carnivores and they prey on fish, anemones, and planktonic organisms.
Octopuses
It is one of the most common cephalopods in the Pacific Ocean. Different species live in different parts of the ocean. The octopus has one of the largest brain-to-body ratios of any species, and also possesses a complex nervous system. Species of octopus vary in size, with the largest being the giant octopus, which can grow up to 50 kg.
Giant squid
The giant squid is a member of the architeutid family ( Architeuthidae). This squid is one of the most elusive Pacific creatures and one of the largest invertebrates in the world (the other being the large Antarctic giant squid). Adults grow up to 13 m in length, and females are relatively larger than males. Giant squids are found in the North Pacific Ocean near Japan.
Pacific white-sided dolphins
Pacific white-sided dolphin - found in the North Pacific Ocean. Animals of this species have a gray back and a creamy white belly and neck. Adult females grow up to 100 kg and have a body length of about 2.2 m, and males weigh up to 180 kg and are 2.3 m long. These dolphins are quite mobile and become victims only of killer whales.
Sea lions
The sea lion is the largest member of the eared seal family ( Otariidae). Adult males can reach a weight of 1000 kg and a body length of 3-3.5 m. This species exhibits sexual dimorphism, and males are larger than females. Males have a massive neck covered with a lion-like mane. These marine mammals are found in the North Pacific Ocean.
Hammerhead sharks
The hammerhead shark is one of the most common sea creatures in the Pacific Ocean. These sharks are easily identified by their head shape, which resembles a hammer. Thanks to this feature, the shark has 360-degree vision. Adult sharks can reach a mass of more than 500 kg and a body length of about 6 m.

The World Ocean The ocean is not just a body of water, it is full of life, sometimes much more diverse than that on land. There are five oceans on earth: the Atlantic, Pacific, Arctic, Southern Arctic and Indian. Scientists estimate the number of ocean inhabitants to be more than two hundred thousand diverse organisms. The permanent inhabitants of ocean waters, in addition to a variety of fish, are crustaceans, cetaceans, turtles, cephalopods (squid, octopuses, etc.), benthos and plankton.

Seaweeds Seaweeds are ancient, layered spore-bearing plants that contain chlorophyll in their cells and live primarily in water. This definition, however, does not give an idea of the enormous diversity in body structure that is characteristic of seaweeds. Here we encounter both unicellular and multicellular organisms, as well as large forms of various structures. Reproduction methods achieve great diversity here. 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.

Corals Coral is the skeletal material of a colony of coral polyps (“bioherms”). Large concentrations of corals form coral reefs and coral islands. The color of corals depends on the composition and amount of organic compounds: not only pink, but also red, blue, white and even black corals are found. Red corals are called “blood foam”, “blood flower”, black ones are called “royal corals”. Pink, red and black corals are considered the most valuable.

Whales Whales are marine mammals from the order Cetacea, not related to either dolphins or porpoises. Killer whales ("killer whales") and pilot whales have the word "whale" in their informal names, although they are strictly classified as dolphins. Whales adopted an aquatic lifestyle approximately 50 million years ago. Cetaceans are divided into two suborders: Whales are marine mammals from the order Cetaceans, not related to either dolphins or porpoises. Killer whales ("killer whales") and pilot whales have the word "whale" in their informal names, although they are strictly classified as dolphins. Whales adopted an aquatic lifestyle approximately 50 million years ago. Cetaceans are divided into two suborders: Baleen whales, distinguished by their baleen, a filter-like structure located on the upper jaw, consisting mainly of keratin. The mustache is used to filter plankton from water. Baleen whales are the largest suborder of whales.

They feed mainly on They feed mainly on fish, shellfish, fish, molluscs, crustaceans; sometimes crustaceans; sometimes they attack their relatives. They are also distinguished by their curiosity and traditionally good attitude towards people.
Crabs The head of crabs is small, the short abdomen is symmetrical and tucked under the jaw-thorax. They live in seas, fresh water bodies and on land. Sometimes the photos reach enormous sizes. A giant crab caught off the coast of Japan had a distance between the ends of its claws of 3.69 m. There are over 6,780 species in the world.

Sharks Sharks are a superorder of cartilaginous fish, including eight orders, twenty families and Sharks are a superorder of cartilaginous fish, including eight orders, twenty families and about 350 species. Representatives of the superorder are widespread in all seas and contain about 350 species. Representatives of the superorder are widespread in all seas and oceans; freshwater sharks are also found. In most oceans, freshwater sharks are also found. Most species belong to the so-called true predators, species belong to the so-called true predators, some species, in particular the whale, giant and some species, in particular the whale, basking and largemouth sharks, feed on plankton. Largemouth sharks feed on plankton.

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 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 of them:
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 Sea stars 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 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
