Sunlight shines through a crack in the sea ice, illuminating sea urchins and starfish. Sea urchins are common scavengers in shallow waters, where they feed on animals trapped in frozen icefall. The icefall is brown due to microscopic algae, which the urchins scrape off and eat. An underwater photography team worked from the US Antarctic Program's base on Ross Island during late spring. Grounded icebergs, frozen waterfalls and sea-ice stalactites form part of an underwater tableau.
