An unusual sight greeted researchers as they captured footage of a large sleeper shark meandering over a desolate seabed in the depths of Antarctica. This unexpected encounter challenged the belief that sharks were absent in the icy waters of the region, according to scientist Alan Jamieson.
The massive shark, estimated to be between three and four meters long, was filmed in January 2025 near the South Shetland Islands by a camera belonging to the Minderoo-UWA Deep-Sea Research Centre. The footage, taken at a depth of 490 meters with a temperature of 1.27 degrees Celsius, revealed the shark’s imposing presence.
Contrary to common assumptions, the shark’s appearance in Antarctica was a surprise as experts typically did not anticipate encountering sharks in this region. The discovery sheds light on the diverse marine life inhabiting the Antarctic Ocean, also known as the Southern Ocean.
Experts noted that the shark seemed unfazed by the presence of a skate, a shark relative resembling a stingray, on the seabed. The sighting of the shark at such a depth suggests that there may be other undiscovered species thriving in the frigid waters of Antarctica.
Researchers highlighted the challenges of studying marine life in Antarctica due to its extreme remoteness and limited access for observation. The footage of the sleeper shark offers valuable insights into the ecosystem of the Antarctic Ocean and underscores the importance of further exploration and research in this unique environment.
