In January 2025, a huge iceberg detached from Antarctica, giving scientists a rare chance to explore a previously unseen section of the seafloor.
During this expedition, researchers captured unique footage of the glacial glass squid (Galiteuthis glacialis), a species first identified in 1906. This marked the first confirmed sighting of a live individual in the wild.
The team filmed the squid at a depth of 687 meters (about 2,254 feet) in the Southern Ocean, near Antarctica. The iceberg, known as A-84, broke off the George VI Ice Shelf, opening a previously hidden ecosystem for study. Researchers from the Schmidt Ocean Institute’s R/V Falkor were thrilled to explore this new area.
Despite having limited knowledge about the glacial glass squid, scientists only had dead specimens to study until this discovery. The footage from January 20, 2025, finally revealed this elusive creature in its natural habitat, offering a glimpse into the life of one of the Southern Ocean’s rarest inhabitants.
Just weeks later, on March 9, 2025, the team recorded the first-ever live footage of the colossal squid (Mesonychoteuthis hamiltoni). Like the glacial glass squid, this species has a transparent body and sharp hooks for hunting. However, the colossal squid can grow up to 7 meters (23 feet), significantly larger than its counterpart. The placement of their hooks also differs: the colossal squid has them along its arms, while the glacial glass squid’s are at the tips of its elongated tentacles.
This research underscores the mysteries of the deep sea. In addition to the squids, the team also documented various other creatures, like icefish and giant sea spiders. Dr. Jyotika Virmani, executive director of the Schmidt Ocean Institute, emphasized, “These unforgettable moments remind us that the ocean is brimming with mysteries yet to be solved.”
With the ocean covering over 70% of our planet and much of it still unexplored, this expedition is a reminder of how much there is left to discover. Each journey into these depths brings new insights and surprises, making the study of marine life a critical field for our understanding of biodiversity and ecosystem health.
Recent research also shows that the Southern Ocean is undergoing rapid changes due to climate change, affecting habitats and the species that rely on them. Keeping an eye on these ecosystems will be essential for conservation efforts.
As we explore the ocean, we tap into a world full of wonders. The more we learn, the better we can protect these vital habitats and the myriad species inhabiting them.
