The Humboldt squid is the largest of the Ommastrephid squids, as some individuals may grow to 1.5 m (4 ft 11 in) in mantle length and weigh up to 50 kg (110 lb). They notably rapidly flash red and white when captured, earning them the nickname diablo rojo (meaning 'red devil') among local fishermen in Baja California, Mexico. Local names for it are jibia in Chile or pota in Peru. Ī general name for this species in Spanish in Latin America is calamar gigante. The name Humboldt refers to the Humboldt Current, off the southwestern coast of South America, where it was first collected. This species is most often known as jumbo squid in English, but has also been called jumbo flying squid or Humboldt squid, with the last name most popular in naturalist sources. The German zoologist George Pfeffer synonymized D. In 1857 the Danish zoologist Japetus Steenstrup proposed the new genus Dosidicus to house the species. In Chile, Claude Gay, another French naturalist, obtained some specimens and sent them to the Muséum national d'Histoire naturelle in Paris, where it was determined that the species did not belong with Loligo either. The French naturalist Alcide d'Orbigny renamed it Loligo gigas in 1835. The existence of this creature was first reported to the scientific world by the Chilean priest and polymath Juan Ignacio Molina in 1782, who named it Sepia tunicata, Sepia being the cuttlefish genus. 7.4 Model organism for early Marine Science in Latin America.This species is spreading north into the waters of the Pacific Northwest, in Oregon, Washington, British Columbia, and Alaska. They are most commonly found at depths of 200 to 700 m (660 to 2,300 ft), from Tierra del Fuego to California. They have a reputation for aggression toward humans, although this behavior may only occur during feeding times. They have a relatively short lifespan of just 1–2 years.

Like other members of the subfamily Ommastrephinae, they possess chromatophores which enable them to quickly change body coloration, known as 'metachrosis’ which is the rapid flash of their skin from red to white. They are the most important squid worldwide for commercial fisheries, with the catch predominantly landed in Chile, Peru and Mexico, however, a 2015 warming waters fishery collapse in the Gulf of California remains unrecovered. Humboldt squid typically reach a mantle length of 1.5 m (4 ft 11 in), making the species the largest member of its family.
