Giant squid show taste for cannibalism

GIANT squid may have a taste for something other than hapless sailors: each other. The creatures, enshrined in myth as ferocious beasts that upturn boats and munch mariners, appear to indulge in cannibalism.

Identifying the prey of the giant squid, Achiteuthis dux, is not easy since they finely macerate their food.

The digestive systems of most specimens studied have been empty and none of the animals has ever been examined alive.
