Why does a mole rat have big teeth?

Answer 1

Mole rats have big teeth primarily for digging and burrowing. Their large incisors are adapted for gnawing through tough soil and roots as they create extensive underground tunnels. These teeth allow them to efficiently excavate their habitats and access food sources, such as underground vegetation. Additionally, their teeth continue to grow throughout their lives, helping them cope with wear from their burrowing activities.
