Humboldt Squid
Humboldt Squid   Class: Cephalopoda   phylum Mollusca





The Humboldt Squid (Dosidicus gigas), also known as the Jumbo Squid, reaches a weight of 50 kg (~110 lbs) and travels in shoals that may contain in excess of a thousand individuals. D. gigas was first described by the renowned naturalist Alexander von Humboldt.

Many reports exist of these aggressive carnivores attacking human beings, particularly divers and fishermen. The suckers lining their tentacles have sharp teeth that tear prey as it is drawn to the sharp beaklike mouth. These squid are also cannibalistic, attacking and eating members of even their own shoal showing signs of disability.

Like many cephalopods, they can change the color of their skins. During attacks on fisherman they have been reported to flash alternately between white and red, behavior that has given them their Spanish nickname, Diablo Rojo (Red Devil).

Geographic distribution: D. gigas was once found only off the western coasts of South and Central America, but it has now expanded its range north as far as Puget Sound.
