A colossal squid has been captured on video for the first time in the deep sea by an international team of researchers using a remotely operated submersible. The Schmidt Ocean Institute announced the sighting on Tuesday. The specimen filmed was a juvenile, approximately 30 centimeters (one foot) in length, and the encounter occurred at a depth of around 600 meters in the southern Atlantic Ocean. Adult colossal squids, which scientists have found in the stomachs of whales and seabirds, can grow up to seven meters (23 feet) long, similar in size to a small fire truck.
The sighting took place last month near the South Sandwich Islands during an expedition aimed at discovering new marine life. Researchers verified the species identification with independent scientists before releasing the footage. The discovery was particularly exciting for squid researcher Kat Bolstad from Auckland University of Technology in New Zealand, who participated in the confirmation. Bolstad noted the beauty of the young squid and expressed optimism about capturing footage of an adult colossal squid using different cameras.
The juvenile squid is almost completely transparent with slender tentacles. As they mature, these squids lose their glassy appearance and develop a dark red or dull purple coloration. Once fully grown, they are considered the largest known invertebrate.
Your World Now
The successful video capture of a colossal squid in its natural habitat provides a significant insight into marine biology and the potential for future discoveries in ocean exploration. This breakthrough may enhance understanding of deep-sea ecosystems and the unique adaptations of creatures residing in such remote environments. It highlights the importance of technological advancements in exploration methods, which can lead to uncovering and preserving previously unknown marine species.
The broader implications of such discoveries extend to environmental conservation efforts and marine policy development. With a greater understanding of marine biodiversity, policymakers can better implement strategies to protect these fragile ecosystems. Additionally, educational outreach may inspire interest in marine sciences, encouraging future generations to contribute to ocean conservation and research.
