What adaptations for getting food and protection from enemies do cephalopods have?

In the integument of the body of cephalopods there are pigment cells. Changing their shape, mollusks quickly change color, disguising themselves to the color of surrounding objects.

They grab food with their tentacles and tear them apart with their beak-shaped jaws.
