Antarctic Expedition Discovers Rare Deep-Sea Squid Species

An expedition led by the Minderoo-UWA Deep-Sea Research Centre and Inkfish, conducted between December 2024 and January 2025, has revealed remarkable footage of rare squid species in the depths beneath the Antarctic Peninsula. Using a remotely operated vehicle (ROV), the team explored the ocean at depths exceeding 1,000 meters.

Rare Squid Sightings Documented

During the expedition, the team encountered several unique cephalopods. At a depth of 1,000 meters, they observed Moratoothopsis longimana, a distinctive ghostly white squid characterized by its elongated tentacles. The researchers also spotted Slosarczykovia circumantarctica, a cephalopod notable for its translucent tissue and luminous eyes.

Perhaps the most surprising discovery was the documentation of Alluroteuthis antarcticus at 1,500 meters. One particularly striking scarlet-red individual was observed clutching its prey. These cephalopods exhibit unique adaptations that enable them to thrive in the sub-zero waters of the Southern Ocean.

For example, the giant Antarctic octopus possesses specialized blue blood, while other species have developed antifreeze proteins. This expedition underscores the rich biodiversity of the Southern Ocean and demonstrates how technological advancements are transforming our ability to explore and understand the ocean's depths.
