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] Historically, G. antarcticus was known to scientists only from dead specimens caught by fishermen and remains found in the bellies of larger animals. However, in December 2024, a free-swimming live squid was captured on video at 7,000 feet by a remotely operated vehicle owned by the Schmidt Ocean Institute making a film for National Geographic.

Distribution

G. antarcticus occurs in waters of the Southern Ocean. Its range may be circumpolar with an Antarctic and Sub-Antarctic distribution. [6] [4]

Ecology

This squid is eaten by several predators in the Southern Ocean, like colossal squid, sperm whales, seals and (when smaller) penguins and albatrosses. [5]

Based on stable isotopes analysis, the squid may be a top predator in its natural habitat. [6] [7]
