40 examples of marine animals –

The ocean is a continuous body of salty water that covers more than 70 percent of the Earth’s surface. Ocean currents govern the world’s climate and stir up a kaleidoscope of life.
Geographers divide the ocean into five major basins: the Pacific, the Atlantic, the Indian, the Arctic, and the South. Smaller ocean regions, such as the Mediterranean Sea, the Gulf of Mexico, and the Bay of Bengal, are called seas, gulfs, and bays.
The oceans contain about 321 million cubic miles (1.34 billion cubic kilometers) of water, which is about 97 percent of Earth’s water supply. Seawater is about 3.5 percent dissolved salt by weight; the oceans are also rich in chlorine, magnesium and calcium. (1)
The seas and oceans have marine species of all kinds.
The oceans are home to millions of plants and animals on Earth, from tiny single-celled organisms to the gigantic blue whalethe largest living animal on the planet. Fish, octopus, squid, eels, dolphins and whales swim in open water while crabs, octopus, starfish, oysters and snails They crawl along the bottom of the ocean.
Life in the ocean depends on phytoplankton, mostly microscopic organisms that float on the surface and, through photosynthesis, produce about half of the world’s oxygen. Other fodder for sea dwellers includes kelp, which are types of algae, and seagrass, which grow in shallower areas where they can catch sunlight.

The deepest reaches of the ocean were once thought to be devoid of life, as no light penetrates deeper than 1,000 meters (3,300 feet). But then hydrothermal vents were discovered. These chimney-like structures allow tube worms, clams, mussels, and other organisms to survive not through photosynthesis but through chemosynthesis, in which microbes convert chemicals released by vents into energy. Strange fish with sensitive eyes, translucent flesh, and bioluminescent lures protruding from their heads lurk in nearby waters, often surviving by eating bits of organic debris and meat that fall from above, or the animals that feed on those bits.
The ocean is home to some of the world’s oldest creatures: jellyfish They have been around for over 500 million years, horseshoe crabs almost as long.

ocean habitat

Ocean habitats are a type of marine habitat: marine habitats include both the oceans and the sea.
The marine habitats they can be very different from each other depending on the temperature of the water. The warm, tropical water has coral reefs full of small, colorful fish. The cold waters in the polar regions have fewer species that have adapted to water that can be colder than the temperature at which water normally freezes!

What wildlife is in an ocean?

Of all the habitats that exist on Earth, none is more biodiverse than the oceans.
Among the thousands (potentially millions) of species that live in the ocean, many of which have yet to be discovered, are animals ranging from sea turtles to blue whales to jellyfish.
About 95% of the creatures that live in the ocean are invertebrates: animals that do not have backbones.

What animal is a marine animal?

The phrase “aquatic animal” can be applied to air-breathing aquatic or marine mammals, such as those of the orders Cetacea (whales) and Sirenia (sea cows), as well as pinnipeds, which cannot exist on land (seals). true, eared seals and the walrus)

Definition of marine animals

The creatures that live in the ocean are known as Marine animals. Marine life, ocean life are terms used to describe oceanic organisms.
Animals, plants and other species can be found in the ocean. Oceanic species vary widely in size, some being microscopic and others gigantic, such as the Piraiba fish from the Amazon, which can weigh up to 200 kg and feeds not only on fish, but also on birds and small mammals.
