All mammals are vertebrates. Being a vertebrate means that they have a backbone.
What are mammals?
Mammals are endothermic animals that have a backbone, mostly give birth to live young, have hair, and have larger brains than a lot of other types of animals.
Some examples of animals are dolphins, monkeys, pigs, sheep, rabbits, horses, and seals.
mam·mal
[mam-uhl]
–noun
any vertebrate of the class Mammalia, having the body more or less covered with hair, nourishing the young with milk from themammary glands, and, with
the exception of the egg-laying monotremes, giving birth to live young.
Types of mammals:
Monotremes: mammals that lay eggs, for example platypus
Marsupials: pouched mammals, for example kangaroo
Placental mammals: in most mammals, the embryo completes its development while protected within the mother
Subtypes:
Insectivora: insect eating animals, for example rats
Chiropetra: mammals having the front four limbs modified as wings, for example bats
Ungulates: mammals with hooves, for example rhino
Aquatic mammals: mammals that live in water, for example whales
Carnivora: mammals that are carnivorous, for example the polar bear
Proboscidea: mammals that are large and include elephants and mastodons
Primates: mammal of the order Primates, which includes the anthropoids and prosimians, characterized by refined development of the hands and feet, a shortened snout, and a large brain, for example humans

Mammal facts
Fastest mammal (also the fastest land animal): the cheetah (60-70 mph = 97-110 kph)
Slowest mammal - the sloth (less than 1 mph, or 2 kph)
Biggest mammal, biggest animal that ever lived on Earth - the blue whale
Biggest land mammal- the African Elephant
Tallest mammal - the giraffe
Smallest mammals - the pygmy shrew (weighing 1.2-2.7 gm) and the bumblebee bat (weighing about 2 gm)
Loudest mammal - the Blue Whale. The second loudest is the Howler Monkey.
Smallest newborns - marsupials (pouched mammals, like the kangaroo)
Smelliest mammal - the striped skunk (Mephitis mephitis)
The only venomous mammals - duckbilled platypus(males only) several species of shrews, and the Solenodon
Fat - The blue whale has the thickest layer of blubber, but ringed seal pups have the greatest percentage of fat (about 50 %.)
Mammals are endothermic, which means they are warm blooded. They are capable of regulating their body temperature.
Mammals have lungs and breath air.
They range from 30 millimeters to 33 meters long.
Although mammals are more advanced, their babies are much less advanced than other animals.
All mammals have a four chambered heart.
All mammals have possession of hair, 3 middle ear bones, and mammary glands.
Moat mammals have sweat glands and specialized teeth.
Mammals sweat or pant to release extra heat inside their bodies if in a hot environment.
It has been estimated that there are about 5500 species of mammals .
Bats are the only mammals that are capable of flying.
The average body temperatures of mammals range from 90-140 degrees Fahrenheit.
Most mammals have varied teeth types including molars, premolars, incisions, and canines.
Mammals have a highly efficient circulatory system.
Mammals have 3 middle ear bones such as, stapes, malleus, and anvil.
Mammals are warm blooded, which means the temperature could be freezing cold or boiling hot, but mammals bodies are built to maintain the right temperature.
According to the website www.earthlife.net/
"Nearly a quarter of all mammals can fly. Yes, it's true, with a huge 985 species bats make up 23.1% of all known mammals by species.
The meek shall inherit the earth, or at least Australia which is a reasonable portion of it. With about 147 million head of sheep, there are about 8 to 9 sheep for every person in Australia.
A prehistoric mammal, the extinct Irish Elk, Megaloceros giganteus, had the largest antlers ever. A specimen found in an Irish peat bog had antlers 4.3 m or 14 ft across which weighed 45kg or 100 lbs.
The Giant Anteater, Myrmecophaga tridactyla, eats over 10,000,000 ants or termites a year.
No two Giraffes have the same pattern of spots and no two Zebras have the same pattern of stripes.
Whales and dolphins sleep one side of their brains at a time - while one side is asleep the other keeps watch for danger.
Sperm Whales can stay submerged for up to two hours descending over a mile below the surface.
The Andes Fishing Mouse was first recorded for science when scientists from the British Mammal Society watching a television programme on the 'Wildlife of the Andes' saw a specimen in the programme and realised that no records of it existed.
Housemice, Mus musculus, have on several occasions been so numerous that they had a population density of over 200,000 per hectare,that's 2 mice for every square metre of land if they were all spaced out evenly.
Rodents, at least the few species that are pests, that cost us about $43 million tonnes of damaged and destroyed food every year."
Some Different Types of Mammals
As you can see, there are many different types of mammals.
Harp Seals like to spend time on land and enjoy swimming. They feed on fish and crustaceans. These seals are also called greenland seals, and saddle back seals because of the dark saddle-like markings on the back and sides of their body. Harp Seals are carnivores and can live up to 20 years. Adult harp seals can weigh up to 400 pounds, and be from 5.25 ft to 6.25 ft long. Harp Seals gather in large colonies on ice floes to molt, breed and give birth. They are also a northern marine mammal, and can stay underwater for up to 15 minutes. Adult harp seals are protected from the cold weather by 3-4 inches of blubber. Harp Seals also range from the North Atlantic to the Arctic Oceans.
Polar bears roam the Arctic ice sheets and swim in that region's coastal waters. They are very strong swimmers, and their large front paws, which they use to paddle, are slightly webbed. Some polar bears have been seen swimming hundreds of miles from land—though they probably cover most of that distance by floating on sheets of ice.Polar bears live in one of the planet's coldest environments and depend on a thick coat of insulated fur, which covers a warming layer of fat. Fur even grows on the bottom of their paws, which protects against cold surfaces and provides a good grip on ice. But under their fur, polar bears have black skin—the better to soak in the sun's warming rays. Females give birth in winter, usually to twins. Young cubs live with their mothers for some 28 months to learn the survival skills of the far north. Females aggressively protect their young, but receive no help from their solitary male mates. In fact, male polar bears may even kill young of their species.
Rabbits are not actually rodents, but in a class called lagomorphs, along with pikas and hares. There are 47 recognized domesticated breeds of rabbits. They range anywhere from 2-16 pounds, and come in short hair, longhair, rex, and satin. They can also have eighther rollback or flyback fur. Rabbit's ears eighther stand strait or flop down, resulting in a lop breed. Very friendly, rabbits are popular pets today, but are often mistaken for a young child's pet, and end up being sent to an animal shelter and often euthanized. Rabbits are placental mammals that give birth to deaf, blind, and helpless babies, called kits, or kittens. They open their eyes 10-14 days after birth, and are completely weaned (separated from their mother) after 8-10 weeks. Males play no role in raising the young. Rabbits live and survive in the wild in a variety of temperatures. They live in deserts, forests, and some even swim!
