An unusual sight was captured when a large, sluggish shark was spotted meandering over a desolate seabed in the deep, dark waters of Antarctica. This surprising discovery defied previous beliefs that sharks did not inhabit the frigid Antarctic region, as researcher Alan Jamieson revealed.
The massive shark, estimated to be between three to four meters in length, was filmed in January 2025 off the South Shetland Islands near the Antarctic Peninsula. The footage was obtained by the Minderoo-UWA Deep-Sea Research Centre, known for exploring life in the deepest parts of the world’s oceans.
The shark, identified as a sleeper shark, was found at a depth of 490 meters in waters with a bone-chilling temperature of 1.27 degrees Celsius. The camera used by the research center captured not only the shark but also a skate, a shark relative resembling a stingray, calmly resting on the seabed near the passing predator.
According to Jamieson, the director of the research center, this was the first documented shark sighting in the Antarctic Ocean. Peter Kyne, a conservation biologist from Charles Darwin University, concurred that such a discovery was unprecedented so far south.
The presence of sharks in the region could be linked to climate change and warming oceans, although data on range shifts near Antarctica is scarce due to its remote location. The elusive sleeper shark population in the Antarctic Ocean remains challenging to study and monitor due to its sparse nature.
The captured shark was observed to be swimming at a consistent depth of around 500 meters, likely feeding on the remains of deceased marine animals that sink to the seabed. The Antarctic Ocean’s complex layering, extending to about 1,000 meters, creates unique conditions that support such deep-sea ecosystems.
Jamieson emphasized the importance of continued research in the region, noting the limited observation windows during the Southern Hemisphere summer months. The discovery underscores the need for further exploration to unravel the mysteries of Antarctica’s marine life.
