Cephalopods

Cephalopods

Squids are cephalopods. The Cephalopods are a class of marine molluscs (soft-bodied animals) that include the octopus, squids, cuttlefish and nautilus. They have a well-developed head (cephalas), large brain and eyes that closely resemble vertebrate eyes in structure. The head is surrounded by prehensile tentacles.

The animals can move very rapidly through jet propulsion, which they generate by squirting water out of the mantle cavity that communicates with the exterior by a siphon or funnel. 
 
(*The mantle is a fold of soft tissue that covers the body of many molluscs and encloses a cavity between it and the body proper.)
