The Sea Butterfly, Staple Morsel of the Arctic Pelagic
by Owen James Burke
The sea butterfly (Limacina helicina) has wings that sprout from its foot which help it to not only stay afloat in Arctic currents, but capture plankton by wrapping them in mucus. They drift along in swarms, making a nice aggregation of food for hungry seals fortunate enough to happen upon them. The seals then feed polar bears, sealing off a small but vital circle of life in the Arctic.
