Sea bears are coastal-dwelling brown bears (Ursus arctos) that have adapted to a life closely tied to marine environments. They inhabit coastal regions across the world's oceans and are known for feeding heavily on fish, crustaceans, and other marine animals, while also supplementing their diet with plants and berries on land. Compared with inland brown bears, these animals typically have thicker fur and a more robust body build. They are often observed swimming and foraging in shallow coastal waters, relying on a strong sense of smell to detect and locate prey.
This group of brown bears illustrates how a terrestrial species can adjust its behavior and diet to coastal environments. Their presence in marine-influenced habitats highlights the flexibility of Ursus arctos in exploiting food sources from both land and sea, contributing to their survival across varied coastal ecosystems.
