Arctic cisco (Coregonus autumnalis) is an anadromous species of freshwater whitefish that inhabits the Arctic parts of Siberia, Alaska and Canada. It also has a close freshwater relative in several lakes of Ireland, known as the pollan, alternatively regarded as conspecific with it, or as a distinct species.
The freshwater omul of Lake Baikal, formerly considered a subspecies Coregonus autumnalis migratorius of the Arctic cisco, has no close genetic relationship to it, and is now classified as a separate species Coregonus migratorius.
Famous quotes containing the word arctic:
“The chisel work of an enormous Glacier
That braced his feet against the Arctic Pole.”
—Robert Frost (1874–1963)
