Research has shown that these tiny little rodents have a high resistance to tumors and other cancer-related disorders. Naked Mole-Rats have a cancer resistance. Because they lack the neurotransmitters, the rodents also do not have the histamine-induced scratching or itching traits that are common in rodents. The skin of the mole-rat has no neurotransmitters which mean that they feel no pain when exposed to such things as acid and capsaicin. This is because their jaws are designed for digging. This is the same percentage humans have in each leg to put it in perspective. 25% of the Naked Mole-Rats muscle mass is in its jaw. The independent movement of the lower incisors is comparable to the movement of fingers, or chop-sticks. Their teeth are used for everything from digging, carrying, eating, fighting, and grooming to transporting the young. The two lower front incisors of a Naked Mole-Rat can be moved independently & voluntarily of each other. The scientific study provided evidence naked mole-rats go into a low energy state and switch to a kind of oxygen-free metabolism that relied on fructose, rather than gloucose. In a zero oxygen environment, the Naked Mole-Rat can live for up to 18-minutes without suffering any harm. It can also live in an atmosphere of 80-percent CO2. Research has revealed that this burrowing rodent can live up to five hours in a setting that has just 5-percent oxygen. The Naked Mole-Rat can live in a zero oxygen atmosphere. They do not have an insulating layer under their skin. This is why they are called ‘naked’ and their skin is a wrinkled pink or yellowish color. They have very little in the way of hair. Naked Mole-Rats eat the underground parts of plants, which means their diet mainly consists of roots or tuber – leaving enough behind for it to survive so they can feed on it again for another meal. They have large protruding front teeth like a miniature walrus that are used to dig with their lips sealed just behind the teeth, which prevent dirt and debris from entering their mouths. They are expert burrowers and amazingly can travel as fast backwards as they can forwards. They have thin and short legs, but easily move underground. The eyes of the naked mole-rat are very small, and this contributes to their poor vision – but they are not blind as is often assumed, and can burrow with eyes closed. The females (called queens) are larger and can weigh as much as 1.8-ounces with the largest recorded at approx. The male mole-rat is between 3 and 4-inches long and will weigh between 1.1 and 1.2-ounces. Naked mole-rats are generally quite small in size. Naked Mole-Rat Facts Overview Habitat:īurrows (in tropical grasslands & deserts) And they are of course, ‘naked’, with very little hair. It is almost completely cold blooded, has no pain sensitivity in its skin, has a very low metabolism, as well as low respiration. They are found in parts of Eastern Africa and has a rather unusual set of physical characteristics that give it the ability to thrive in a harsh underground environment. They are more closely related to porcupines and guinea pigs. Despite the name, they are neither moles, or rats. The Naked Mole-Rat (Heteroephalus glaber) also known as the Sand Puppy, is a rodent that typically burrows.
