Humboldt squid live at depths of 660 to 2,300 feet in the eastern Pacific, ranging from Tierra del Fuego north to California. They take their name from the Humboldt Current in which they live off the coast of South America. Recently, the squid have been appearing further north, as far as Sitka, Alaska. Jumbo squid can reach up to six feet and weigh as much as 100 pounds. Their skin varies from deep purplish-red to white. Like other cephalopods, muscle-bound chromatophores on their skin enable them to flash a range of colors. They have two diamond-shaped fins which they use to swim and glide.
