With their torpedo-shaped bodies, powerful suckers, and acute senses, as well as their fitness to move or cover themselves with stupendous quickness, squid are among the most sophisticated of all ocean hunters.
Squid belong to the group of mollusks known as cephalopods, which also includes octopuses and cuttlefish. The word “cephalopod” means “head-foot.” In cephalopods, the muscular foot seen in most other mollusks has been modified into powerful, suckered tentacles that are attached to the front of the head.
