Gonatus antarcticus

Gonatus antarcticus is a squid in the family Gonatidae. The species is known with certainty only from southern Atlantic waters but it may have a circum-Antarctic distribution.[3][4]

Class: Cephalopoda
Order: Oegopsida
Family: Gonatidae
Genus: Gonatus
Species:
G. antarcticus

Gonatus antarcticus

Distribution

G. antarcticus occurs in waters of the Southern Ocean. Its range may be circumpolar with an Antarctic and Sub-Antarctic distribution.[5][4]

Ecology

This squid is eaten by several predators in the Southern Ocean, like Albatrosses, Sperm whales, Seals and Penguins.

Based on stable isotopes analysis, this squid may be a top predator on its natural habitat.[5][6]
