Minimum depth from Ref. 117401. Death of this species can result from predation by polar bears and killer whales, ice entrapments and diseases. There are at least seven (7) stocks of belugas in the North American Arctic based on mitochondrial and nuclear DNA markers (Ref. 118436). Found in shallow coastal waters, and occasionally moves into deep, offshore waters. In the summer, they aggregate in large numbers in shallow estuaries. They primarily feed on various species of fish, combined with a wide variety of mollusks and benthic invertebrates which are found on or near the bottom (Ref. 1394).
