This wolverine was captured foraging for fish beneath a frozen arctic spring along the Shaviovik River, Alaska. Wolverines in this region often dine on snowshoe hares, caribou and voles. It is thought to be the first-known observation of a wolverine eating fish. The research, published in the Journal of Ecology, is part of an ongoing project by the Wildlife Conservation Society on how wolverines use permafrost. 📸 BBC #wolverine, #hunting, #alaska, #permafrost, | New Scientist
