What is mammal short answer?
What is a mammals? Mammals are vertebrates with hair, mammary glands used to suckle young with milk, a diaphragm, three bones in the middle ear, and a lower jaw made up of a single pair of bones that articulates in a unique way with the skull.
Short and simple answer: mammals are animals that produce milk to feed their babies. Most of them also give birth (although the platypus and echidna, found in Australia, lay eggs). Their bodies are covered in hair rather than scales or feathers, or they are mostly hairless but descended from hairy ancestors.
Mammals include humans and all other animals that are warm-blooded vertebrates (vertebrates have backbones) with hair. They feed their young with milk and have a more well-developed brain than other types of animals.
Mammals are a group of vertebrate animals. Examples of mammals include rats, cats, dogs, deer, monkeys, apes, bats, whales, dolphins, and humans.

What do mammals eat?
Some groups of mammals almost exclusively eat meat--take lions and tigers and other big cats as examples. Other mammals such as deer, cows and antelope are predominantly plant-eaters, living on a diet of leaves, shoots, fruits and bark.
Mammals undoubtedly play an important role in ecosystems by providing essential services such as seed dispersal, pollination and regulating insect populations, and reducing disease transmission [20–22] and there is some evidence that some groups act as indicators of general ecosystem health [23].
Sharks are fish, even though some people believe they are mammals due to how big some of them can get and because some give birth to live young. Fish are aquatic animals that were among the first vertebrates (animals with a backbone) to evolve on earth.
No, birds are not mammals. Rather, they are avians. Mammals are characterized by their milk glands, hair, vertebrae and their birthing of live young (being viviparous), according to Britannica. Additionally, mammals are warm-blooded, says WorldAtlas.
Bats are the only mammals that actually fly, flapping their wings to propel them in flight. Some mammals, such as flying squirrels, only glide rather than fly. Because bats are unique they are classified in their own special order of mammals, called Chiroptera.
Two characteristics are used to define the mammal class. They are mammary glands and body hair (or fur). Female mammals have mammary glands.
A majority of mammals live on land, although some are aquatic and some are aerial, and a few are “fossorial” (live underground). Of the land mammals, many live in trees and have larger limbs (and occasionally tails) to help them get from tree to tree. The primary species of aerial mammals is the bat.
Mammals inhabit every terrestrial biome, from deserts to tropical rainforests to polar icecaps. Many species are arboreal, spending most or all of their time in the forest canopy.
Mammal. Humans are likely the most numerous species of mammal on Earth at the moment.
Mammals are separated into three main groups based on how they reproduce: monotremes, marsupials, and placentals mammals.
Do mammals lay eggs?
As for us mammals, only two types lay eggs: the duck-billed platypus and the echidna. After a three-week pregnancy, the short-beaked echidna of Australia makes a nursery burrow, where she lays her egg directly into her pouch, incubating it for ten days until it hatches into a baby.

After elephants and rhinoceros, the hippopotamus is the third-largest land mammal and the heaviest surviving land artiodactyl.
Hair is present in differing degrees on all mammals. On adult whales, elephants, sirenians, and rhinoceroses body hair is limited to scattered bristles. In most other mammals the hair is abundant enough to form a thick coat, while humans are among the most hairless of all mammals.
Organisms which are heterotrophic, can move from one place to other, do not contain cell wall and have definite growth, this is referred as Animals. Organisms which are warm blooded animals, have mammary glands and body is covered with hair, this is referred as Mammals.
All mammals and birds are capable of generating this internal heat and are classed as homoiotherms (ho-MOY-ah-therms), or warm-blooded animals. Normal temperatures for mammals range from 97° F to 104° F.

Mammals (from Latin mamma 'breast') are a group of vertebrate animals constituting the class Mammalia (/məˈmeɪli.ə/), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones.
Mammals have hair or fur; are warm-blooded; most are born alive; the young are fed milk produced by the mother's mammary glands; and they have a more complex brain than other animals.
