Most representatives of the rodent family,despite the widespread bad opinion about them, are useful for people. They destroy insects and prevent weeds from growing, thereby maintaining the purity of the forest. And, of course, rodents are also suppliers of valuable and beautiful fur. All kinds of these animals can not be listed in one article, but we will try to highlight the most important points.
Rodents live in burrows, and in winter they go into hibernation.Due to these qualities they are better than others can tolerate poor living conditions. Also, these animals multiply rapidly even in an unfavorable environment and in captivity. Practically in all places on the globe (with the exception of Antarctica and other few points) live rodents. All species, the number of which exceeds 1,5 thousand, are about 30 families, the most common of which are the following:
Representatives of this mammal, as alreadymentioned above, can be found everywhere, both in the tropics and in cold zones. Despite this, animals practically do not differ in structure. A long tail, a mustache and a compactly folded body are the main signs that rodents have. All kinds (photos of some representatives can be seen in the article), as a rule, have 5 fingers on the paws in front. Sometimes one final element may be absent or be rudimentary, that is, a residual element that has lost its value.
Also, mostly these animals are stooping.The shape of the tail in the members of the detachment can be determined by the functionality. Thus, in the beaver this part is wide and flat, like the fin, which helps the animal very much when swimming. And the mouse-baby has a narrow and plastic tail that allows it to climb on the grass.
As a rule, most of the representatives of this detachment wear fur very fluffy and soft. However, in some species, the hair was regenerated into hard needles, as, for example, in the porcupine.
As you know, some representatives of thisThe detachment can be kept in captivity for various purposes, and others - just as pets. Home rodents (species for growing) are, as a rule, rabbits, nutria, guinea pigs and so on. For each representative of individual families, there are different requirements for content.
So, for muskrat and nutria it is recommendedprepare a free habitat, for example, to protect a sufficient area on the backyard. For squirrels, hamsters and other small animals, it is enough to equip the cage. It is possible to single out general requirements to the conditions of rodents:
