In a monumental achievement for marine biology, video footage of a juvenile colossal squid has finally been captured after a staggering century with no visual documentation of these elusive creatures in their natural environment.

On March 9, a remotely operated vehicle from the Schmidt Ocean Institute recorded this mesmerizing sighting near the South Sandwich Islands, approximately 430 miles southeast of South Georgia Island in the South Atlantic Ocean.

This isn't just any colossal squid; it's an adorable baby! This juvenile's transparent body glimmers like glass, showcasing its internal organs and featuring mesmerizing, glowing eyes paired with gently swaying orange tentacles.

Observation revealed that the squid has two curved hooks adorning the clubs at the ends of its long tentacles, along with additional hooks on the middle of its eight arms—crucial traits of these giant denizens of the deep.

At roughly a foot long and residing at a depth of 1,968 feet, this young squid is still in its early stages of life. As it matures, it will lose much of its transparency and can grow up to an astonishing seven feet and weigh as much as 1,110 pounds, claiming its title as the heaviest invertebrate on Earth.

Despite their daunting size and fascinating biology, much of the colossal squid's life remains shrouded in mystery, primarily due to their elusive nature and deep-sea habitat. While instances of them being found in the stomachs of sperm whales hint at their ecological role, capturing footage in their underwater realm marks a groundbreaking moment for researchers.

Curious about oceanic life? Alongside this spectacular squid footage, there are mesmerizing documentaries available for viewers eager to dive deeper into the mysteries of the sea. From thrilling accounts of encounters with marine life to breathtaking visuals of underwater ecosystems, here's a roundup of some must-watch deep-sea documentaries.
