Wild animals, the list of which many know yetfrom school, belong to the class of mammals. This is not the most numerous group of living things on the planet. However, their representatives are at the top of the food chain. Wild animals are called those that live in natural natural conditions.
Reproduction of mammals
All wild animals, the names, list and classification of which will be discussed further, have one thing in common: mothers are fed by cubs with milk. Reproduction takes place in several ways.
Oviparous wild animals go by birds and reptiles. However, the hatched cubs are fed with milk. A typical oviparous animal is the platypus.
Viviparous marsupials. Their offspring are born before the moment of full development and moves to the special hatcher bag. Kangaroo is a typical representative of this type of animal.
Viviparous placental.The most numerous group. Females of these species have a placenta - a special organ for bearing young. It helps to exchange substances between the embryo and the mother. The process of maturation of the offspring is completed in the womb of the mother organism. The cubs are born already fully formed. Marsupial and oviparous animals do not have a placenta.
Signs of mammals
Wild animals, the list of which detachments contains20 items have common features. All of them are of different sexes, each species has male and female individuals. Pregnancy of the female comes only after fertilization by the male. Hatching of babies lasts different number of days: from 12 to 600. After birth, they can not do without mother's milk, protection and care. Life expectancy varies from 1 year to 70 years, depending on species.
Wild animals, the list of which is quite extensive, by type of food can be divided into three categories:
- herbivores;
- carnivorous;
- omnivorous.
Constant body temperature is present in the vast majority of wild animals. They have high adaptive abilities, so mammals have adapted to life in different ecological niches.
Wild animals of Russia
Wild animals on all continents are inhabited by suchthe amount that one of their enumeration will take a long time. On the territory of the Russian Federation there are about 300 species of mammals. The variety of climatic zones allows to cover many ecological niches. The list of wild animals in Russia will give an idea of what species live here. Man over the past hundred years markedly reduced the composition of the fauna of our country.
