For the first time, a colossal squid was filmed in its natural habitat, a juvenile specimen near the South Sandwich Islands at a depth of 600 meters. The footage, captured during a 35-day expedition, reveals a 30cm-long squid, a species that can grow up to 7 meters long and weigh 500kg. This discovery, marking the centennial of the species’ identification, provides invaluable insights into the elusive colossal squid’s life cycle, previously known mostly from remains found in marine animal stomachs. The team also captured the first-ever footage of a glacial glass squid, highlighting the vast unexplored biodiversity of the Southern Ocean.

Colossal squid filmed by scientists for the first time in the ocean, a truly remarkable event considering the elusive nature of this deep-sea behemoth. This recent footage captures a juvenile colossal squid, measuring a mere 30 centimeters in length, a far cry from the colossal adults that can reach lengths of up to seven meters and weigh a staggering 500 kilograms. The filming took place near the South Sandwich Islands in the south Atlantic, at a depth of 600 meters, during a month-long research expedition dedicated to discovering new marine life.
The discovery holds immense scientific value, marking the first time a colossal squid has been observed in its natural habitat. This allows scientists to glean crucial insights into its behavior and natural life cycle, information previously lacking due to the immense challenges of observing these creatures in their deep-sea environment. Before this footage, most encounters involved dead specimens found in the stomachs of sperm whales or incidentally caught in fishing nets.
The sheer size and weight of adult colossal squid make them the heaviest known invertebrates on Earth. Their deep-sea existence, coupled with their lack of need for air, means they rarely, if ever, venture close to the surface. The youngest among them typically reside at depths exceeding 500 meters, with adults dwelling even deeper. This deep-sea habitat explains the difficulty in observing them and the relative scarcity of knowledge about these fascinating creatures. Their elusiveness has earned them a place among the most enigmatic animals on the planet.
Often compared to giant squid, colossal squid are, in fact, not closely related. While giant squid might potentially achieve greater lengths, colossal squid are significantly heavier and bulkier. This emphasizes the unique characteristics and ecological role of the colossal squid within the deep-sea ecosystem.
The footage has generated considerable excitement within the scientific community and beyond, sparking discussion and speculation about the implications of this discovery. The filmed juvenile’s small size underscores the vast unknown concerning the life cycle and growth patterns of this species, opening up new avenues for research and exploration. The possibility of larger, undiscovered species in the deep ocean has also been raised, fueling imaginations and inspiring playful suggestions about new names, from “mega squid” to “gargantuan squid” or even humorous “baby squid” conventions.
This event also highlights the importance of continued deep-sea exploration and research. The mysteries surrounding colossal squid, along with other deep-sea inhabitants, still far outweigh the current knowledge base. The footage serves as a powerful reminder of the vastness and richness of the ocean and the remarkable life forms it harbors, while also provoking reflection on the potential consequences of human activity on these deep-sea environments. The need to balance scientific curiosity with responsible environmental stewardship in future explorations is undeniably significant.
The fascination with colossal squid isn’t simply scientific; it extends to the realm of mythology and popular culture. Many believe colossal squid are the inspiration for the legendary Kraken, although visual depictions often bear a closer resemblance to octopuses. The image of a massive squid lurking in the deep, arising from dark waters to confront sailors, has long captivated imaginations and fueled countless tales of sea monsters. The reality of a colossal squid, while still awe-inspiring, may not quite match the fantastical descriptions, yet the discovery undeniably fuels the deep-seated fascination with the ocean’s unknown depths.
The small size of the filmed squid, barely a foot long, has been met with a mix of reactions, ranging from disappointment to amusement and even critical commentary about misleading headlines and the need for better scaling in the footage. However, the overall consensus celebrates the groundbreaking nature of the observation. The discovery serves as a springboard for future research efforts aimed at unraveling more about the natural history and behaviour of colossal squid, while simultaneously emphasizing the need to protect the vulnerable deep-sea ecosystem. The footage provides a rare glimpse into a world largely unexplored and underscores the importance of continued investigation into this truly extraordinary species.
