Rare Sleeper Shark Spotted in Antarctic Deep, Scientists Say
A Minderoo-UWA Deep-Sea Research Centre camera off the South Shetland Islands captured a 3–4 meter sleeper shark at about 490–500 meters depth in near-freezing 1.27°C water, possibly the first confirmed record of a shark that far south in the Antarctic Ocean; researchers note such sightings are rare due to remoteness and limited deep-water cameras, and warming oceans could be nudging species toward Antarctica.
