Most are pelagic, meaning they live near the water's surface in shells, reefs and crevices. Some species live on the floor of the ocean, making their homes out of caves.

Octopuses tend to be solitary, though they do interact with other octopuses at times. Some species of octopuses hunt at night, while others only hunt at dusk and dawn. When scared, octopuses will shoot a dark liquid, sometimes called ink, at the thing that scared them. This will temporarily blind and confuse a potential attacker, giving the octopus time to swim away. Octopuses can also change color to hide and match their surroundings.

They can turn blue, gray, pink, brown or green. The mimic octopus can also flex its body to resemble more dangerous animals, such as eels and lionfish, according to the World Animal Foundation. If an octopus does get caught — no problem. They can lose arms and regrow them, according to National Geographic.

Octopuses are fast swimmers but they prefer to slowly crawl along the sea bottom. To swim, octopuses suck water into their bodies and shoot it out a tube called a siphon, according to the World Animal Foundation. This lets the octopus blast off, away from attackers.

Octopuses are carnivores, which means they eat meat. Meals can include clams, shrimp, lobsters, fish, sharks and even birds. Octopuses typically drop down on their prey, envelop it with their arms and pull the animal into their mouth.

Octopuses have short life spans. Some species only live for around six months.
