Here's why:
* Digging: Moles are expert burrowers and use their claws to dig through soil, creating tunnels for shelter, foraging, and raising their young. The shape and strength of their claws allow them to efficiently move dirt and create stable tunnels.
* Food: Moles are insectivores, meaning they eat insects. Their strong claws help them unearth worms, grubs, and other insects from the soil.
So, while not "sharp" in the traditional sense, their claws are undeniably essential for their survival and are a testament to their incredible digging abilities.
