* Opportunistic Feeders: Polar bears are opportunistic feeders, meaning they take advantage of whatever food is available. Carcasses, especially those of seals and other marine mammals, can be a valuable source of nutrients.
* Food Scarcity: During lean times, when hunting seals is difficult (for example, during the summer months when sea ice melts), carcasses become an important food source.
* Survival Strategy: By scavenging, polar bears can conserve energy and reduce the risk of starvation, especially for mothers with cubs or for bears in poor physical condition.
While polar bears primarily hunt seals, their diet isn't limited to fresh kills. They are known to scavenge on carcasses left by other predators, including walruses, whales, and even other polar bears. This adaptation helps them survive in their challenging environment.
