Ice entrapments of narwhals (Monodon monoceros) and white whales (Delphinapterus leucas) in Greenland
Information on historical and recent ice entrapments of narwhals (Monodon monoceros) and white whales (Delphinapterus leucas) in Greenland is presented. Most entrapments occur in the inner parts of Disko Bugt where both narwhals and white whales are caught. In this area entrapments happened under pa...
