Humboldt squid


The Humboldt squid (Dosidicus gigas), also known as jumbo squid or jumbo flying squid (EN), and Pota in Perú or Jibia in Chile (ES) is a large, predatory squid living in the eastern Pacific Ocean. It is the only known species of the genus Dosidicus of the subfamily Ommastrephinae, family Ommastrephidae.

Humboldt squid typically reach a mantle length of 1.5 m (4 ft 11 in), making it the largest member of its family. They are the most important squid worldwide for commercial fisheries, with the catch predominantly landed in Mexico, Peru and Chile. 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 have a relatively short lifespan of just 1–2 years. They have a reputation for aggression toward humans, although this behavior may only occur during feeding times.

They are most commonly found at depths of 200 to 700 m (660 to 2,300 ft), from Tierra del Fuego to California. This species is spreading north into the waters of the Pacific Northwest, in Oregon, Washington, British Columbia, and Alaska.

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. The French naturalist Alcide d'Orbigny renamed it Loligo gigas in 1835. 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. In 1857 the Danish zoologist Japetus Steenstrup proposed the new genus Dosidicus to house the species.[3]

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.[5] The name Humboldt refers to the Humboldt Current, off the southwestern coast of South America, where it was first collected.[6]

A general name for this species in Spanish in Latin America is calamar gigante.[7][8] Local names for it are jibia in Chile[9] or pota in Peru.[10] 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.[11]
