Sleeper shark surprises scientists with rare Antarctic camera sighting

Researchers captured video of a 10–13 ft sleeper shark around 1,600 feet deep off the South Shetland Islands near the Antarctic Peninsula, challenging the belief that sharks don’t inhabit Antarctic waters. The sighting, recorded by a deep-sea camera, suggests sharks may occur farther south than previously documented, though such populations are likely sparse and data-limited due to remoteness and seasonal camera access. Climate change could influence future range shifts in the region.
