Octopuses are highly intelligent animals which live in the ocean. Scientists say that these marine creatures are as intelligent as dogs.
Octopuses have a soft and round body with no bones or shell. They move by crawling and swimming.
Octopuses have eight arms. They can regrow an arm if they lose one. They use their arms to crawl on solid surfaces and to grab food.
Octopuses have special skin cells. This allows them to change the color of their bodies. When under attack, they often send out black ink to escape from hunters.
Octopuses often hunt at night. They feed on crabs, shrimps, and shellfish.
Octopuses do not live very long. Some species live as shortly as six months. Others may live up to five years.
