Cephalopods are swimming marine molluscs that have eight to ten tentacles around their heads and well developed eyes.
They have an internal shell (cuttlefish and squid) or no shell (octopus).
Molluscs are soft-bodied animals (from the Latin mollis = soft), generally protected by a shell which can be simple, with plates or with two valves.
They have gills or lungs and a muscular foot, transformed in cephalopods into tentacles.
