A groundbreaking discovery has left marine biologists in awe: a shark has been caught on camera for the first time in the waters of Antarctica. This remarkable footage challenges long-held beliefs about the presence of deep-sea sharks in the region.
For years, many experts believed that sharks did not inhabit the frigid waters of Antarctica. However, a recent video, captured in January 2025, reveals a substantial shark, estimated to be between three and four meters long, swimming in the depths of the Antarctic seabed. The researcher and founding director of the Deep-Sea Research Centre at the University of Western Australia, Alan Jamieson, expressed surprise at the discovery, stating, 'We went down there not expecting to see sharks because there’s a general rule of thumb that you don’t get sharks in Antarctica.'
The camera, operated by the Australian research facility, was positioned off the South Shetland Islands near the Antarctic Peninsula. The shark was spotted swimming at a depth of 490 meters, in temperatures hovering just above 1°C. Jamieson explained that the shark was in the warmest of several water layers stacked on top of each other, which may explain its presence in the region. He also noted that there are no other records of any shark swimming in the Antarctic Ocean.
Another expert, Peter Kyne, a conservation biologist from Charles Darwin University, agreed that this was an unprecedented observation. Kyne attributed the scarcity of data on sharks' travel patterns and ranges in the region to its remoteness, suggesting that climate change could be a contributing factor. However, he also considered the possibility that the slow-moving sleeper sharks were already in Antarctica, but nobody had ever noticed.
Jamieson added that the sleeper shark population in the Antarctic Ocean may be small, making them hard to spot. The Antarctic Ocean is heavily layered to a depth of around 1,000 meters due to its conflicting properties, and Jamieson suspects that other sharks may be lingering at the same depth, feeding on whale carcasses, giant squid, and other sunken marine life.
This discovery has significant implications for our understanding of marine ecosystems in the region. It also raises questions about the potential impact of climate change on the distribution and behavior of deep-sea sharks. As Jamieson noted, 'The other 75 percent of the year, no one’s looking at all. And so this is why, I think, we occasionally come across these surprises.'
The mysterious depths of the Antarctic Ocean are home to only a handful of seemingly otherworldly sea creatures, including the mackerel icefish, which has colorless blood due to its lack of hemoglobin, and the Antarctic cod, which has antifreeze proteins in its tissues and blood. Similarly, anglerfish, distinguished by a bioluminescent bulb on their heads, large mouths, and sharp teeth, were first documented in Antarctic waters in 2014 and are commonly found at depths of between 1,000 and 2,000 meters.
This groundbreaking discovery invites further exploration and research into the Antarctic Ocean's unique marine life. It also prompts us to reconsider our assumptions about the distribution and behavior of deep-sea sharks. As Kyne noted, 'It’s quite significant.'
