Here's why:
* Bears are land mammals: They live in forests and mountains, far from the ocean where tuna live.
* Diet: Bears are primarily carnivores and omnivores, consuming a variety of foods like berries, nuts, insects, and larger prey like fish, deer, and elk. Tuna is a saltwater fish and not part of their natural diet.
While bears might occasionally eat fish they catch in rivers and streams, it's highly unlikely they'd ever encounter tuna in the wild.
