The little auk is a small seabird from the alcid family. It lives in cold northern seas, forms huge colonies, and swims well underwater.
The little auk differs from other alcids by its very small size and diet mainly consisting of zooplankton. It is important for Arctic nature because it transfers nutrients from the sea to land and serves as food for predators.
Immature form that undergoes metamorphosis before adulthood.
