They Naked Mole Rat, Sand puppy or Heterocephalus glaber are Rodentia bathyergidae single species. Typical individuals are 3 to 4 in. long and weigh 1.1 to 1.2 oz. Queens are larger and may weigh well over 1.8 oz., the largest reaching 2.8 oz. They are well-adapted to their underground existence.
Naked mole rat or Heterocephalus glaber eyes are quite small, and their visual acuity is poor. Their legs are thin and short; however, they are highly adept at moving underground and can move backward as fast as they can move forward.
Their large, protruding teeth are used to dig and their lips are sealed just behind the teeth, preventing soil from filling their mouths while digging. About a quarter of their musculature is used in the closing of their jaws while they dig. They have little hair and wrinkled pink or yellowish skin. They lack an insulating layer in the skin.
Naked mole rats or Heterocephalus glaber feed primarily on very large tubers (weighing as much as a thousand times the body weight of a typical mole-rat) that they find deep underground through their mining operations.
A single tuber can provide a colony with a long-term source of food—lasting for months, or even years, as they eat the inside but leave the outside, allowing the tuber to regenerate. Symbiotic bacteria in their intestines ferment the fibers, allowing otherwise indigestible cellulose to be turned into volatile fatty acids.
They do not regulate its body temperature in typical mammalian fashion. They are thermoconformers rather than thermoregulators in that, unlike other mammals, body temperature tracks ambient temperatures. At lower temperatures, naked mole rats can use behavioral thermoregulation. Cold naked mole rats huddle together or seek shallow parts of the burrows that are warmed by the sun.
