What Is a Squid Mantle

The main part of the body containing all the organs is called the mantle. It is the pocket of skin that covers the body. The mantle is covered in pigment cells called chromatophores. Squids can change color rapidly and they use this to camouflage themselves, to attract mates, and to communicate with each other.

What is the function of the mantle in cephalopods?

The mantle is highly muscular. In cephalopods the contraction of the mantle is used to force water through a tubular siphon, the hyponome, and this propels the animal very rapidly through the water. In gastropods it is used as a kind of “foot” for locomotion over the surface.
