Colossal Squid Filmed in Deep Sea for First Time

Fast Summary

• A juvenile colossal squid was filmed in its natural deep-sea habitat for the first time by an international research team using a remotely operated submersible.
• The sighting occurred near the South Sandwich Islands in March 2025, at a depth of 1,968 feet (600 meters) and was announced on April 16, 2025, by the Schmidt Ocean Institute.
• The squid filmed measured approximately 1 foot (30 cm), while adults can grow up to 23 feet (7 meters).
• Researchers waited for external verification from independent scientists before confirming and releasing footage of the species.
• Squid expert Kat Bolstad from Auckland University emphasized the significance of filming a juvenile and described its appearance as “gorgeous.”
• Juvenile colossal squids are nearly obvious with thin arms but mature into dark red or purple adults. Full-grown colossal squids are considered the largest known invertebrates.

Indian Opinion Analysis

The successful capture of imagery showing a juvenile colossal squid marks an important milestone in marine biology and exploration. Such findings contribute not only to our understanding of unique life forms but also to broader ecological insights concerning deep-sea biodiversity-a frontier still largely unexplored across global oceans. For India, advancements like this underline how oceanographic technologies can aid similar endeavors domestically; particularly considering India’s vast maritime boundaries ripe for exploration under initiatives like ‘Deep Ocean Mission.’ Collaborations such as those seen here present opportunities for Indian researchers to engage at global levels while enhancing domestic capacities for marine conservation and exploration science.
