The squid/cuttlefish distinction

Squid, Octopus, Cuttlefish is a brief but informative page.

SquidWith their stream-lined, torpedo-shaped body, excellent eyesight and active swimming lifestyle, squid seem to be more similar to fish than to other molluscs. Unlike cuttlefish which are mostly solitary, squid often move about in shoals. They lack the internal chalky bone of the cuttlefish, relying instead on a thin membrane called the pen, for support. When disturbed, squid squirt a cloud of black ink into the water to help mask their escape.
