What is an ocean?

The ocean has been called the new frontier. The great body of water embracing the continents of the Earth is also known as the world ocean. Some people divide the world ocean into the North Pacific, South Pacific, North Atlantic, South Atlantic, Indian, Arctic, and Antarctic - a total of seven. The term seven seas, however, originated with medieval Arabic geographers who knew only the waters of Europe and Asia. Oceans cover more two - thirds of Earth's surface. The Gulf of Mexico is larger than most seas. Waves wash up on a beach along the coast of Brazil. An Ocean is a huge body of water. Oceans cover nearly 71 per cent of Earth surface. They contain almost 98 per cent of all the water on Earth. The five major oceans cover most of Earth's surface. The largest ocean animal is the blue whale and the colour fish swim through a coral reef.

Whale shark

The whale shark is the largest fish in the world. It us also an endangered species, which means that it is in danger of disappearing forever. The scientific name of the whale shark is Rhincondon typus. Whale sharks live in warm waters around the world. They are found in the Atlantic, Pacific, and Indian oceans. Whale sharks are 12 and 15 metres ( 39 to 49 feet) long, but they can grow as long as 18 metres ( 59 feet). They can weigh 20 tons. Whale sharks are blue, grey or brown on top, with pale yellow spots and stripes. Whale sharks swim very slowly. The young whale sharks care for themselves from the day they are born. The whale sharks can live from 60 to 100 years.

Seahorse

Seahorses are small fish that swim upright. They're named seahorses because of their horse-like head. Seahorses live in warm shallow waters oceans, near the shore. Seahorses have long bodies covered in rings of bony plates rather than scales. There are more than 30 species of seahorses. Seahorses have no teeth and no stomach. Seahorses use their dorsal fins to propel slowly  forward and to move up and down, seahorses adjust the volume of air in their  swim bladders. The made seahorse carries the eggs in her pouch for 2 to 3 weeks before giving birth. The lifespan is approximately 3 years. They can have as many as 2,000 babies at a time. 

Sea  turtle

﻿

Sea turtles can be found in oceans all over the world. There are seven species, and they are are split into two families : the Dermochelyidoe  family and the Cheloniidae. The sea turtles come in all different sizes and colours. The leatherback is the largest sea turtles  and its shell can be as long as eight feet. Ridley's are the smallest, with a shell size about 23 - 31 inches long. As adults, both species have shells about 23 - 31 inches  ( 58 - 78 centimetres ) long.

Octupus

The name of octupus  comes from a Greek word meaning ` eight - footed ,` and this sea creature is distinguished by its eight tentacles. They are usually called arms. The octupus is a soft - bodied animal known as a mollusc and is related to the squid. There are more than150 different kinds of octupus. They live in all oceans except the Arctic. Octopuses are mollusk, which are soft - bodied animals. Octopuses are similar to squid and cuttlefish. They have no bones  or shells that would give their body rigid form. Octopuses very greatly  in size. The smallest are about 5 centimetres ( 2 inches ) long. The largest may grow to 5.5 metres ( 18 feet ) in length and have an arm span  of almost 9 metres ( 30 feet ). The octopus can change its colour quickly depending on its surroundings. Octopuses skilfull  hunters they eat mainly crabs and lobsters but they also attack large preys such as sharks. The female  Kay's her eggs under rocks or in holes.

Dolphins

Dolphins are known for their intelligence and playfulness. They live all over the world in both salt water and freshwater. But they are not fish. They are mammals. There are more than 35 species, or kinds, of dolphins.  True dolphins live in oceans. Dolphins can be found throughout the world. The larger dolphin can reach a length of 4 metres ( 13 feet ).

Loggerhead  and green sea turtle have adult shell length between 3 and 4 feet ( 0.9 and 1.2 metres ) long. Eggs incubate for about 50 to 60 days. Most species if sea turtles are threatened or endangered. They are typically slow to mature, long - lived   , and migratory. Many are captured - either intentionally or accidentally - in coastal fisheries and killed.

Dolphins are social animals,  meaning that they generally live in schools. The dumping of chemicals and other waste into the water  may position the dolphin's food supply and make the dolphins I'll. Another danger is pollution of the world's oceans.

Conclusion

If you would like to live on the Earth with fresh air and would like to see more of these animals don't throw plastic in the ocean because then all of the creatures will die so use and clean after yourself !
