A juvenile colossal squid was recorded in the deep sea for the first time by a group of international researchers. The event occurred near the South Sandwich Islands in the South Atlantic Ocean during a scientific expedition held last month. The squid was observed at a depth of 1,968 feet (600 meters) using a remotely operated submersible. The captured squid measured approximately 1 foot (30 centimeters) in length. According to marine scientists, colossal squids are rarely seen alive, and most information about them has come from remains found inside whales and seabirds. Adult colossal squids can grow up to 23 feet (7 meters), making them one of the largest invertebrates in the world. The research team announced the discovery after confirming the species with multiple independent experts. The video footage was made public on April 15, 2025, by the Schmidt Ocean Institute.

The squid’s appearance was described as nearly transparent, with long, delicate arms, unlike the dark red or purple coloration seen in fully grown adults. Experts believe this finding is a significant breakthrough, as it offers a rare glimpse into the early life stage of a mysterious species. A squid specialist from Auckland University of Technology in New Zealand expressed appreciation for observing the juvenile form, calling the animal aesthetically remarkable. Researchers are currently using advanced camera systems to capture additional footage and hope to document an adult specimen in the future. The discovery highlights the importance of deep-sea exploration and underscores the technological advancements that enable access to remote ocean ecosystems, which remain largely unexplored and enigmatic.
