Collared Lemming—Winter
As snow starts to fall, lemmings grow oversize claws on the third and fourth toes of their front feet. This allows them to dig tunnels in the snow all winter. Staying below the surface helps them avoid predators while they shovel in search of food. By spring, their intense burrowing wears down their claws to a normal size again.
