Huge icefish colony of 60 million nests found on Antarctic seabed

Researchers exploring Antarctica’s seabed have discovered a thriving, unprecedented colony of icefish 'about a third of the size of London'. 'We expected to see the normal Antarctic seafloor … [but] during the first four hours of our dive, we saw nothing but fish nests,' said Autun Purser, of the Alfred Wegener Institute for Polar and Marine Research in Germany, and lead author of the study published in Current Biology.
