All mammals have stereoscopic vision, which gives them depth perception. Moreover, in the case of hunters such as tigers, their night vision is six times keener than that of humans. There are many species that have a very keen sense of smell, and the sense of taste is closely linked to that of smell.

Hair, too, performs various functions in these animals’ lives – conserving body heat, providing protection and serving as camouflage.


Mammals share a series of characteristics that distinguish their class: a body covered by hair, the birth of live young and the feeding of newborns on milk produced by the females mammary glands. All breathe through lungs and all processes a closed circulatory system and the most developed the nervous system in the animal kingdom.


The ability to maintain a constant body temperature has allowed them to spread out and concure every corner of the earth, from the coldest climate to hot deserts and from the mountains to oceans.

1. A body for every Environment

Skin covered with hair and sweet glands helps create and maintain a constant body temperature. At the same time, with eyes placed on each side of the head, they are folded important angles of sight. Limbs are either of the foot or chiridium type, with sight variations depending on the part of the foot used for walking.

In aquatic mammal, the limbs have evolved into fins, in bats, into wings. Hunters have powerful claws have strong hooves that support the whole body when running.

2. Mammals Hair

Body hair is unique to mammal and absent in other classes of animals. Sirenians, with little hair and cetaceans are exceptions, in both cases, the absence of hair is a result of the mammal’s adaptation of an aquatic environment.

3. Mammals Dentition

The majority of mammal change definition in their passage to adulthood. Teeth are specialised for each function: molars for chewing, canines for tearing and incisors for gnawing. In rodents, such as chipmunks, the teeth are renewed by continuous growth.

4. Homeothermy

The ability to keep body temperature relatively constant independent of the ambient temperature. Hibernating species are the exception. They must lower their body temperature to enter into this state of reduce metabolic activity. Contrary to popular belief, bears do not truly Hibernate but rather into a period of deep sleep during winter.

5. Mammals Limbs

They have four limbs that are adapted for moving about on land. There are four limbs have certain other abilities (swimming, manipulation, attack and defence, protection). The exceptions are the cetaceans, so adapted to Marine life that they have only two fingerless limbs and seals.

6. Take habitat into account

between every mammal and its natural habitat there is a relationship that exist and is expressed in the animal’s physical characteristics. just as the flippers of the elephant seal are used to swim and hunt fish, mimicry and running are vital for dear. psychology is a special instrument of adaptation to the environment as in the case of camel. There are following habitat of the mammals.

  • Aquatic
  • Temperate Forests
  • Desert
  • Meadow or pastureland
  • Tropical Savanna
  • Tropical rain forest
  • Taiga
  • Tundra

Mammals are homeothermic – which means they are capable of maintaining a stable internal body temperature despite environmental conditions. Visibility has allowed them to establish themselves in every region of the planet.

Homeo status is achieved by a series of processes that tend to keep water levels and concentrations of minerals and glucose in the body in equilibrium as well as prevent and accumulation of waste products among other things.

Grace and Movement

Mammals Qualities, Grace and Movement
Grace and Movement

Horses, one of the odd-toed, hoofed, ungulate mammals, are considered symbols of Grace and freedom. They have great vigour and can run swiftly because their spine bends very little, preventing unnecessary expenditure of energy during the rising and falling of their body mass. They are equipped with strong light and flexible bones and their muscles work by contraction are in pairs or groups that pulls in opposing directions.

Mammals Extremities

Mammals Extremities are basically either of the foot or chiridium type but are modified according to the way in which each species moves about. thus for example they become fins for swimming in aquatic mammals and membranous wings in bates.

Inland mammals these variations depend on the way the animal wears its weight in walking: those that have used the whole foot are called plantigrades. Those that place their weight on their digits, digitigrades and those that only touch the ground with the tips of their phalanges, ungulates.

Mammals behaviour

Mammalian production is sexual and by internal fertilization which involves capsulation between the male and female. Mammals are also characterized by the offspring dependence on its parents in any case. There is a group of mammal call monotremes that is oviparous, its members reproduce by laying eggs.

Mammalian behaviour consists of a mixture of inherited components and components that can be shaped by learning. Part of this process is accomplished through play, since the young use such encounter to practice jumping, beating, hunting and other survival skills.

Mammals Life Cycle

Birth maturity reproduction and death: this life cycle had certain particulate is among mammals. As a general rule, the larger a mammal the longer the members of its species tend to live but the fewer offspring are born to a single female per litre or reproductive season.

Most mammals including humans are placental mammals; their vital functions are fully developed inside the body of the mother.
