Well There are the grey wolves who live in the mountains but the wolves who live so close to the sea in sections called The Great Bear Rainforest they're considered Sea Wolves sometimes. These Sea Wolves eat more fish and berries than grey wolves in the polar areas and have to use more viligance because the bear families outnumber them. The wolves who are considered Sea Wolves are expert swimmers. Gray Wolves in Alaska's mountains have to deal more with icicles, icy cliffs, ice covering rivers, and high piles of snow. The Arctic wolves let their food depend on where they've chosen a den, they're one of the main Arctic animals.
