There are several types of mole rodents, known more commonly in scientific circles as mole rats. The most common mole rodents are the blind mole rat, naked mole rat and Damaraland mole rat. These rodents are best known for their propensity to burrow.
Mole rodents are typically small and gray in color. Their size ranges from 5 to 10 cm in length, and most specimens bear long, tapering snouts. Mole rodents tend to lack ears, and their eyes are barely discernible. These rodents have stubby, broad, shovel-like front teeth, which have been adapted for digging. Their incisors protrude when their mouths are closed.
Some mole rodent species are known for their social behaviors, which are similar to those of ants, bees and termites. Colonies include complex social structures wherein there is one female, known as the queen. The other colony members serve as workers. Workers are divided by a continuum of behaviors. Most workers are dedicated to tunneling, while some serve as soldiers. This social structure is extremely rare among mammals.
