Habitat
The octopus lives on the bottom of oceans and seas, but some octopuses will use the currents along the bottom of the seabed to move from place to place.
Diet
Octopuses eat small crabs and scallops, plus some snails, fish, turtles, shrimp, and other octopuses. They catch prey with their arms, then kill it by biting it with their tough beak, paralyzing the prey with a nerve poison, and softening the flesh. They then suck out the flesh. Octopuses hunt mostly at night. Only the Australian Blue-ringed octopus has a poison strong enough to kill a person.
Movement
Sometimes it crawls, other times it moves by pushing water out of its body through the siphon.
Description
An octopus has a soft body and eight arms. Each arm has two rows of suction cups. If it loses an arm, it will eventually regrow another arm. It has blue blood. An octopus has an eye on each side of its head and has very good eyesight. An octopus cannot hear.
Enemies
Adult octopuses main predators are eels and sharks. Baby octopuses spend a period of time floating as clouds of plankton before they drop down to the bottom of the ocean. Plankton eaters such as sharks and whales take many young octopuses. The predators of an octopus also include seals, some whales and sharks, larger fish and even other octopuses. Sea turtles are even able to eat octopuses.
