These rotund animals have a hairless, pointed snout, small eyes and no visible ears. On average, moles grow to 4.4 to 6.25 inches (11.3 to 15.9 centimeters) long from snout to rump. Their tails add 1 to 1.6 inches (2.5 to 4 cm) of length. They typically weigh 2.5 to 4.5 ounces (72 to 128 grams), according to the Mammal Society.
Moles are insectivores, eating 70-100% of their weight in worms, grubs and insects each day. In order to hunt down their ground-dwelling prey, moles constantly excavate, leaving behind a series of tunnels. This digging requires a tremendous amount of energy, which may explain the mole's voracious appetite.
