Are beluga the average prey of U.maritimus, or indeed, are beluga even an average maritime mammal?

Polar bear's prey mainly on seals (ringed and bearded) but their teeth can still slice through thick skin.  I think bear's jaws are made the way they are based on their diet (just as the kea's beak is made different from other parrots).

Sloth bear's diet:

Quote:Food/Eating Habits

As animals who consume termites and ants, sloth bears are considered myrmecophagous. When trees are in fruit, usually during the monsoon season, sloth bears dine on mango, fig, ebony and other fruits, as well as on flowers.
Termites, dug out of their cement-hard nest mounds, and some ants are year-round staples. During non-fruiting season, insects constitute 95 percent of a sloth bear's diet. Sloth bears climb trees and knock down honeycombs, later collecting the honey from the forest floor. Beetles, grubs and other insects round out their diet. During food shortages, sloth bears will eat carrion. They also sometimes raid farm crops.
The Smithsonian's National Zoo's sloth bears eat a dry-food mixture designed for omnivores, plus fruits and vegetables, such as apples, sweet potatoes and grapes. At the Zoo, they are offered food at least three times daily: a large morning meal, a large evening meal and one or more snacks throughout the day. They also receive treats as enrichment, such as mealworms, crickets, nuts, coconut and honey.

Sloth bear's do not need that strong jaws based on their diet and when they eat carrion, they prefer the softer parts (I believe sloth bear's have the weakest slicing and crushing bite out of all bears) while polar bears have the best slicing bite. The best crushing bite goes to the giant panda because of its diet on tough bamboo.
