Scientists operating a remotely operated vehicle captured video of a living colossal squid at a depth of 600 meters [1].
The encounter provides rare visual evidence of one of the ocean's most elusive predators in its natural habitat. Because these creatures typically reside in the deep ocean, sightings of live specimens are infrequent and critical for understanding their behavior.
The footage was recorded near the South Sandwich Islands in the Southern Ocean [1]. The ROV was conducting a survey when it inadvertently encountered the animal [1].
There are conflicting reports regarding the maximum size of the species. One source said that adult colossal squid grow to 23 feet, or approximately seven meters, and can weigh up to 1,100 pounds [1]. Another report said the creatures can grow over nine meters long [2].
These animals play a significant role in the deep-sea food web. Data suggests that colossal squid make up around 80 percent of the diet for sperm whales in the Southern Ocean [2].
The specimen filmed during this expedition was described as a teenager [1]. This suggests that the captured footage represents a younger individual rather than a fully grown adult, though the sighting still confirms the presence of the species in the region.

The accidental recording of a juvenile colossal squid highlights the challenges of deep-sea biology, where most knowledge of a species is derived from carcasses or stomach contents of predators. The discrepancy in reported maximum lengths, ranging from seven to over nine meters, underscores the lack of standardized data on a species that is nearly impossible to study in a controlled environment.
