Ice Fish
Living in 10m (32ft) below the surface of the Southern Ocean, where temperatures hover around -2 °C (28.4 F), are fish that seem to be made of the ice they swim beneath. Antarctic icefish are so well-adapted to the frigid waters, they even have an antifreeze glycoprotein in their blood and body fluids to stop ice crystals forming. (source: bbc)
