What is naked mole?
Naked Mole Rat is a very unusual rodent coming from the desert in East Africa. She lives in Burrows and has developed a number of features that exist in their harsh environment. The naked mole rat is hairless and almost cold -blooded and its skin does not register pain. His teeth grow off their mouths so that they can use them to play without ingesting dirt. The most common of all is the naked molová Rat Eusocial, a feature shared by only one other mammal, Damaraland Mole Rat. Each colony has a queen who has about twice the size of typical mole. The colonies consist of about 75 to 80 mole rats living in up to two or three miles (three to five km) of tunnels. The naked mole rats feed mainly on the large tubers that they find underground. They only eat the inside of the tubers and skin that leave, allow the plants to regenerate.
eusocatiness, social structure more common in insects, especially ants and bees, relies on most women in the population that gives up their reproductive skills to take care of POtoma of one woman, queen. One to three men connect with the queen, and the rest of the colony are specialized workers who can dig tunnels, feed offspring or prevent the colony from predators. The queen of the queen lives a naked mole for about 15 to 18 years and after her death is replaced by another queen. Every year, a litter produces typically three to twelve young. Other rats can live in some cases for the past 20 years.
In order to live in an underground environment poor in oxygen, they have small rats on the mole small lungs and their blood is incredibly effective in absorption of oxygen. They are unable to regulate their body temperature to the extent that they are virtually cold -blooded and their metabolism is slow, unlike most mammals of their size, retains oxygen. They can also reduce their metabolic rate by up to 25 percent in the period of famine, which may be responsible for its longevity.
Mole also lack a neurotransmitter called a substance in their skin. This neurotransmThe iter, common to most mammals, sends pain signals to the central nervous system. It has been suggested that naked molnic rats developed this adaptation because their limited oxygen supply causes acid to accumulate in their tissues, which would cause pain if the animals had a substance p.
