The strange-looking octopus has a bulbous body and eight arms. Its bag-shaped body, called a mantel, houses a remarkable well developed brain and nervous system, making the octopus surprisingly intelligent.
A bottom-dwelling animal, the octopus makes its home in a hole or rock crevice in shallow water. Sometimes it digs a gravel nest or forms a protective area with a pile of rocks.
By day, the octopus spends most of its time hidden in its lair. When it hunts, it propels itself up by swimming or crawling along on its tentacles. It large, lidded eyes are adapted to focus in dim underwater light.
The octopus does most of its hunting at night. It emerges from its rocky lair to seek crabs, crayfish, and mollusks, which are its favorite foods.
