The octopus belongs to a subclass of cephalopods. They are symmetrical, with two eyes and four pairs of arms. While the octopus is a cephalopod, which is very different from its relatives, such as oysters and snails. It is more closely related to the squid.
The octopus has no shell; it has a hard beak, with its mouth at the center. Since they do not have a skeleton, they can squeeze into tight spaces and their favorite place is coral reefs.
Octopus usually moves by crawling and swimming. When they want to travel slowly, they tend to crawl with some swimming.
When they crawl, they actually walk on their arms. Typically, they use a lot of legs at the same time on hard and soft surfaces. Octopuses can also walk on two arms.
For eating, the octopus uses its strong jaws that look like a parrot’s beak. It can bite hard and at the same time it inject its venom. Octopuses eat mainly crabs, polychaetes worms and other molluscs, such as mussels and whelks. Open ocean octopuses eat mainly shrimp, fish and other cephalopods.
