Cephalopods are found in all of the world's oceans.


Cephalopods are found in tide pools, on sea bottoms, and swimming in open water. They live at depths of 16,400 feet (5,000 meters) or more.


Most cephalopods prey on fishes, crustaceans, and mollusks, including other cephalopods. However, nautiluses and their relatives scavenge dead animals.


No species of cephalopods are considered threatened or endangered.
