Scientists have captured the first-ever footage of a living colossal squid in its deep-sea Antarctic habitat. The video, taken by a remotely operated vehicle at a depth of nearly 2,000 feet, shows a juvenile squid, approximately one foot long. Experts confirmed its identity based on distinctive arm hooks. This discovery is a significant breakthrough in understanding this elusive creature, the world's heaviest invertebrate, known for its massive size and large eyes.
