Scientists have captured the first confirmed video of a juvenile colossal squid, Mesonychoteuthis hamiltoni, in its natural habitat near the South Sandwich Islands, 100 years after the species was first identified. Filmed by a remotely operated vehicle at a depth of 600 meters, this nearly 30 cm squid provided new insights into the elusive creature’s life cycle.

Experts say this “teenager” squid bridges the knowledge gap between hatchlings and adults. Unlike the giant squid, the colossal squid is found only in Antarctic waters. The video revealed signature features such as arm hooks and rusty red chromatophores.Research vessel Falkor (too) maneuvers around icebergs while conducting research in the Bellingshausen Sea off Antarctica.

This rare footage, along with a separate sighting of the glacial glass squid, highlights how little we know about deep-sea life. Though an adult colossal squid remains unseen, scientists hope future expeditions will bring them closer to understanding this mysterious species.
