A colossal squid has been filmed in its natural habitat for the first time, providing scientists with a rare opportunity to study these elusive creatures up close. The juvenile squid, measuring about 12 inches in length, was recorded nearly 2,000 feet below the surface of the South Atlantic Ocean.
Researchers at the Schmidt Ocean Institute captured the footage using an underwater vehicle operated by a remote crew. Dr. Kat Bolstad, an associate professor at Auckland University of Technology, verified the footage and said it’s exciting to see a juvenile colossal squid in its natural habitat.
The discovery sheds light on why colossal squids have remained elusive for 100 years, with their large eyes likely causing them to avoid research equipment. However, this new footage may provide scientists with more information about how colossal squids behave early in their lives.
The juvenile squid displayed pearly eyes and transparent organs, typical of the Cranchiidae family, also known as “glass squids.” As it matures, its muscles will thicken, making it more opaque. This is a significant finding, as scientists still know little about the diet, lifespan, or reproductive traits of colossal squids.
The footage was captured by Thom Linley, an expert in deep-sea fish who worked on the ship gathering notes for a upcoming dive. He initially caught a glimpse of the squid and quickly sent a low-resolution image to Dr. Bolstad, which was later confirmed as authentic by independent scientist Aaron Evans.
The discovery highlights the importance of continued research into these mysterious creatures. Colossal squids are found exclusively in the deep sea near Antarctica and can reach lengths of up to 23 feet and weigh over 1,100 pounds, making them one of the heaviest known invertebrates.
