 | | Cephalopods are mollusks and therefore are related to bivalves (scallops, oysters, clams), gastropods (snails and slugs), scaphopoda (tusk shells), and polyplacophorans (chitons). |
 | | Cephalopods are an ancient group that appeared some time in the late Cambrian several million years before the first primitive fish began swimming in the ocean. |
 | | Cephalopods were once one of the dominant life forms in the world's oceans. |
