What characteristics describe moles?

Moles are unique mammals that are characterized by their anatomy and behavior. They possess a pointed snout, which is well adapted for their burrowing lifestyle, allowing them to effectively navigate through soil in search of insects and earthworms, their primary food sources. Additionally, moles have large, powerful claws that are specially designed for digging. This adaptation enables them to create extensive underground tunnel systems efficiently. These traits distinguish moles from other animals and are crucial for their survival in their preferred habitat, which is typically moist and rich in organic material.

The other choices describe animals that do not match the characteristics of moles. For example, small rodents that build nests in trees refer to different species altogether, and flying insects that feed on plant roots do not share any of the physical traits or ecological roles of moles. Ground-dwelling mammals that live in colonies could suggest several social animals, but moles are solitary creatures rather than forming colonies. Hence, the defining characteristics of moles align perfectly with the traits mentioned in the correct answer.
