Marine animal studies overview

Two sightings of Polar Bears (Ursus maritimus) with dead Beluga Whales (Delphinapterus leucas) on ice were made by aerial teams looking for Bowhead Whales (Balaena mysticetus) during their spring migration near Point Barrow, Alaska, from 1985 to 1992.Along with other sightings of Belugas being killed and eaten by Polar Bears reported in the literature, these records suggest that Belugas may make an important contribution to the diet of Polar Bears in some areas.
