What is Moles: Definition and 207 Discussions

Moles are small mammals adapted to a subterranean lifestyle (i.e., fossorial). They have cylindrical bodies, velvety fur, very small, inconspicuous ears and eyes, reduced hindlimbs, and short, powerful forelimbs with large paws adapted for digging.
The term mole is especially and most properly used for "true moles" of the family Talpidae in the order Eulipotyphla, which are found in most parts of North America, Europe and Asia, although it may also refer to unrelated mammals of Australia and southern Africa that have convergently evolved the "mole" body plan.
Moles are known pests to human activities such as agriculture, lawncare, and gardening. They do not eat plant roots, but cause damage indirectly by eating earthworms and other small invertebrates in the soil. While moles may be viewed as pests, they do provide many positive contributions to the soil, gardens, and ecosystem, including soil aeration, feeding on slugs and other small creatures that do eat plant roots, and providing prey for other wildlife.
