The Humboldt squid (Dosidicus gigas), also known as jumbo squid, jumbo flying squid, pota or diablo rojo, is a large, predatory squid living in the waters of the Humboldt Current in the eastern Pacific Ocean. Dosidicus gigas is the only species of the genus Dosidicus of the subfamily Ommastrephinae, family Ommastrephidae.
Humboldt squid are among the largest of squids, reaching a mantle length of 1.5 m (4.9 ft). They have a reputation for aggression towards humans, though this behavior may possibly only manifest during feeding times. Like other members of the subfamily Ommastrephinae, they possess bioluminescent photophores and are capable of quickly changing body coloration (metachrosis). They notably rapidly flash red and white while hunting, earning them the name diablo rojo (Spanish for 'red devil') among fishermen. They can live for up to two years.
They are most commonly found at depths of 200 to 700 m (660 to 2,300 ft), from Tierra del Fuego to California. Recent findings suggest the range of this species is spreading north into the waters of Oregon, Washington, British Columbia, and Alaska.[1][2] They are fished commercially, predominantly in Mexico and Peru. |
