In brief
In a historic find, researchers captured footage of a juvenile colossal squid in the South Sandwich Islands, marking a significant advancement in marine biology.
In March 2025, Kathrin S.R. Bolstad returned from an Antarctic expedition equipped with a state-of-the-art camera system designed for locating the rare colossal squid, Mesonychoteuthis hamiltoni. Although Bolstad did not observe the elusive creature herself during her expedition, an exciting twist awaited her upon her return. On March 9, a team from the Schmidt Ocean Institute, while diving near the South Sandwich Islands, recorded footage of a young colossal squid measuring about 30 centimeters (just under one foot) in length. This juvenile squid exhibited a translucent body adorned with delicate arms and brown spots, piquing the interest of marine biologists worldwide.Recognized for their size, adult colossal squids can grow up to 7 meters (around 23 feet) and are considered the largest invertebrates on the planet, even surpassing the giant squid. Despite their enormity, these fascinating creatures have been notoriously elusive, with no successful live sightings recorded until this recent encounter.Dr. Bolstad, a cephalopod specialist at Auckland University of Technology, expressed her excitement at seeing the footage, stating, "Pretty much as soon as I saw the footage, I knew there was a good chance." Her consultation for the Schmidt team showcases the collaboration between scientists dedicated to unveiling the mysteries of our deep oceans.This remarkable find reaffirms the importance of ongoing marine exploration and sheds light on the enigmatic life of one of nature's most extraordinary cephalopods, paving the way for further studies and conservation efforts.
