Why do Polar bears eat mussels?

Polar bears eat mussels primarily because they are a source of protein and fat, which are essential for their energy needs, especially in the harsh Arctic environment. During times when traditional prey like seals may be scarce, mussels can provide a more accessible food source. Additionally, as opportunistic feeders, polar bears will consume a variety of foods available in their habitat to supplement their diet. This flexibility helps them survive in changing environmental conditions.
