Symbiotic bacteria in their intestines ferment the fibres, allowing otherwise indigestible cellulose to be turned into volatile fatty acids. In fact, those kept in zoos are kept under low lights. For the reason that there is very little oxygen underground, the naked mole rat is well adopted for this by having very small lungs. Unlike the females, there are usually multiple reproducing males. Naked Mole Rat. A pup is born blind with an average weight of just 2 grams. They live in clusters and on average a cluster has about 80 naked mole rats, although this number can be higher than this. She will get rid of any competition and will note this by sensing the females that are producing hormones so as to become queens. Bioimages at Vanderbilt University.

When they are injected with substance P , a type of neurotransmitter, the pain signaling works as it does in other mammals but only with capsaicin and not with acids. The measurements of females before they became reproductive and after show significant increases in body size. University of Chicago Press. Naked mole-rats' substance P deficiency has also been tied to their lack of the histamine-induced itching and scratching behavior typical of rodents. They live in clusters averaging 75 to 80 individuals. PLoS Biology. Clusters averaging 75 to 80 individuals live together in complex systems of burrows in arid African deserts. Naked mole-rats 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.

Naked mole-rats have a high resistance to tumours, although it is likely that they are not entirely immune to related disorders.

Although this animal is known as the naked mole rat but it is neither a rat nor a mole. Wikimedia Commons Wikispecies. Only color. They lack a neurotransmitter which makes them unable to transmit pain sensations from the skin and this is an important adaptation to the environment that they live in. Heterocephalus glaber. This occurs through the workers keeping the pups from straying, foraging for food, grooming, contributing to extension of tunnels, and keeping them warm.

The measurements of females before they became reproductive and after show significant increases in body size. There are two main types of worker, the "frequent workers" who frequently perform tasks such as foraging and nest building and "infrequent workers" that show role overlap with the "frequent workers" but perform at a much slower rate.

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. The workers are sterile and cannot reproduce and therefore they only focus on getting food and taking care of the nest. 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.
