Squid : Calamari

Squid is an animal without vertebarae .

Squid are cephalopods of the order Teuthida, which comprises around 300 species.

The giant axon, which may be up to 1 mm (0.04 in) in diameter in some larger species, innervates the mantle and controls part of the jet propulsion system.

Like all cephalopods, squid have complex digestive systems. The muscular stomach is found roughly in the midpoint of the visceral mass. From there, the bolus moves into the caecum for digestion.

The majority are no more than 60 cm (24 in) long, although the giant squid may reach 13 metres (43 ft).
