The first confirmed live observation of the colossal squid
ROV SuBastian/Schmidt Ocean Institute
The colossal squid, known as Mesonychoteuthis hamiltoni, has been captured alive in its natural habitat for the first time. This remarkable discovery was made by a team aboard the Schmidt Ocean Institute’s Research Vessel Falkor during an Ocean Census expedition in the remote South Sandwich Islands in the South Atlantic Ocean. The footage was captured at a depth of 600 meters using a remotely operated vehicle named SuBastian on March 9.
Scientists have long been fascinated by the colossal squid, which is considered the largest invertebrate on Earth. Previously, knowledge of this elusive creature was limited to fragments found in the stomachs of whales or specimens that washed ashore. The species was officially described in 1925 based on these remains.
Despite occasional encounters with live colossal squids, including one caught in fishing nets in 1981, observing this creature in its natural habitat has remained a rare occurrence. The recent footage provides valuable insights into the behavior and appearance of these mysterious deep-sea dwellers.
The recorded squid, measuring 30 centimeters in length, is believed to be a juvenile. Adult colossal squids can reach lengths of up to 7 meters and weigh up to 500 kilograms. The distinctive hooks along the suckers on its arms confirmed its identity as a colossal squid.
Dr. Jyotika Virmani of the Schmidt Ocean Institute expressed excitement about the discovery, highlighting the continuous exploration and discovery of new marine life in the deep sea. This sighting adds to the growing body of knowledge about these enigmatic creatures.
Prior to this observation, there were reports of a possible colossal squid sighting in 2023 by researchers from Kolossal, another non-profit organization. The comparison between the two sightings raises the possibility of a consistent presence of colossal squids in the Southern Ocean.
Despite these advancements, much about the life and habits of colossal squids remains unknown. Formerly described as “seriously evil denizens of the deep,” these creatures are now viewed as gentle giants that roam the ocean depths. Further research and observations are needed to unravel the mysteries surrounding these fascinating marine creatures.
