Top: A lone gentoo penguin on Cuverville Island on the Antarctic Peninsula. This site is host to the peninsula’s largest known gentoo penguin colony, about 6,500 pair. Left: A southern elephant seal. Right: This iceberg’s golf-ball-like surface is caused by the movement of tidal waters around the ice. When the icebergs flip, these undersides are exposed.
