Mammals

A mammal is an creature that feeds its babies with milk when information technology is young. At that place are over 4,500 types of mammals. Many of the nearly popular animals nosotros know are mammals, for instance, dogs, cats, horses, cows, but exotic animals similar kangaroos, giraffes, elephants and anteaters belong to this grouping, as well. Humans are besides mammals.

Mammals alive in all regions and climates. They alive on the ground, in trees or undercover. Polar bears, reindeer and seals are mammals that live in the Arctic regions. Others, like camels or kangaroos prefer the world's dry areas. Seals and whales are mammals that swim in the oceans; bats are the simply mammals that tin can fly.

Mammals have 5 features that brand them different from other animals:

• Female mammals produce milk and feed their babies with it.
• Simply mammals have hair or hair-like skin. All mammals have hair at least some time in their lives.
• Mammals are warm-blooded. Their body temperature ever stays the same and does not modify with the exterior temperature.
• Virtually mammals have a larger and well-adult brain. They are more intelligent than other animals.
• Mammals protect their babies more than than other animals. They prepare them for future life.

People have hunted mammals for ages. They ate their food and made dress out of their skins. Thousands of years agone wild mammals were domesticated and gave human beings milk, wool and other products. Some mammals, like elephants and camels are withal used to send goods. In poorer countries farmers use cows or oxen, to plough fields.

Today some mammals are hunted illegally. Whales are killed because people want their meat and oil, elephants are killed for the ivory of their tusks.

Mammals are ofttimes kept as pets. Among them are cats, dogs, rabbits or guinea pigs.

Mammals are useful to people in many other means. Some aid plants grow and eat harmful insects. Others eat weeds and prevent them from spreading as well far. The waste matter of mammals is used as fertilizers that improve the quality of soil.

Types of mammals

Mammals are divided into three groups:

1. Monotremes are mammals that lay eggs, like a bird. They live in Australia and New Zealand. The platypus belongs to this group
2. Marsupials are mammals that raise their young ones in a pouch in their bodies.
3. Placentals are the largest group of mammals. The babies grow inside their mothers until they are ready to be born. Humans are placentals.

Mammals and their bodies

Skin and hair cover a mammal'south torso. Some mammals have horns, claws and hoofs. The pilus or fur of a mammal has many functions. The colour often blends in with the world around them and allows them to hide from their enemies. Some mammals produce needles or sharp hair that protects them from attack. But the main function is to keep the body warm.

Mammals have glands that produce substances that the body needs like hormones, sweat and milk.

A mammal's skeleton is made upward of three parts:

1. The skull contains the encephalon, teeth and other organs.
2. The spine or courage enables mammals to stand or walk.
3. Limbs are legs and arms of a mammal, often with stiff basic.

Mammals take a iv-chambered eye system that pumps claret into all parts of their torso. The blood brings oxygen to muscles and tissue. The cerise blood cells of mammals can carry more than oxygen than in many other animals. Because mammals take a high body temperature they must burn a lot of food.

Mammals assimilate food through their digestive organisation. After food is eaten through the oral cavity information technology goes down the pharynx into the stomach and passes through the intestines. Mammals that eat plants have a complicated system with long intestines that help pause downwardly food. Flesh is easier to assimilate so meat-eating mammals accept a simpler stomach.

Mammals breathe air through their lungs. Nigh of them have noses or snoutswith which they take in air. Dolphins and whales breathe through a hole in the superlative of their back.

Mammals and their senses

Mammals have five senses that tell them what is happening in their surroundings. Non all senses are developed equally among mammals.

Mammals rely on smell to notice food and warn them of their enemies. Many species utilize smell to communicate with each other. Humans, apes and monkeys take a relatively bad sense of aroma.

Taste helps mammals place the food that they eat. Near mammals have a good sense of hearing. Some mammals use their hearing to detect objects in the dark. Bats, for example, use sounds to navigate and detect tiny insects. Dolphins also utilise such a  system to find their way effectually.

While higher primates, like humans, apes and monkeys have a highly developed sense of sight other mammals are virtually blind. Virtually of these mammals, similar bats, are active at night.

Mammals have a expert sense of touch. They have nerves on all parts of their trunk that let them feel things. Cats and mice have whiskers with which that they can experience themselves around in the dark.

What mammals swallow

Herbivores are mammals that eat plants. They have special teeth that allow them to chew food better. Examples of herbivores are deer, cows and elephants. The giant panda is a plant eater that only eats bamboo.

Carnivores are mammals that eat other animals. Cats, dogs, tigers, lions, wolves vest to this group. They are hunters that tear their prey autonomously with sharp teeth. They do non chew their food very much.

Omnivores are mammals that eat plants and meat. Bears, , apes, pigs and humans are examples of omnivores.

How mammals move

Most mammals live and move on the ground. They have 4 legs and walk by lifting one human foot at a time or by trotting. Kangaroos hop and utilise their tail for balancing.

Mammals that live in forests spend a lot of their fourth dimension in trees. Monkeys can grasp tree branches with claws and tin hang on to them with their curved tail. Often mammals spend fourth dimension hanging upside down in trees.

Dolphins and whales are mammals that live and motion around in water. Instead of limbs they have flippers which they use to move forwards. Other animals, like the hippopotamus, only spend some time in the water.

Bats are the only flight mammals. Their wings are made of skin stretched over their basic. They tin fly by beating their wings up and down.

Gophers and moles are mammals that spend most of their life underground.

How mammals have babies

Mammals reproduce when a male's sperm gets into contact with a female egg and fertilizes it. A young mammal grows within the female's body. Before this can happen mammals mate. Males and females stay together for a sure time.

Unborn mammals live their mother'due south trunk for dissimilar periods of time. While hamsters are built-in afterwards only 16 days, it takes elephants 650 days to requite nascence. Human pregnancies last about ix months.
Many new-born mammals, similar horses and camels, can walk and run before long later on they are born.

Marsupials give birth to babies that attach themselves to their mothers. They stay in pouches because they are as well weak to alive lonely. Almost all marsupials, including kangaroos, koala bears or wombats live in Australia .

After birth the glands of a female mammals produce milk. Some mammals nurse their babies for just a few weeks. Others, for example elephants, give milk to their babies for a few years.

The duck-billed platypus and echidnas are the only mammals that lay eggs. After the young hatch they beverage milk from their mother, just like other mammals practise.

Life habits

Many mammals live in families or groups. Wolves and lions help each other in their search for food and protect each other from attackers.
Leopards, cats, tigers and other mammals prefer living alone . They do not share their living space and nutrient that they have, however males and females get together to mate.
Mammals can mark the areas that they live in. They defend these areas by fighting off attackers. Some mammals claim territories merely during the convenance season.

Many mammals migrate during special times of the twelvemonth in order to get food and survive. North American bats travel to the south because insects become deficient during the common cold winter months. Zebras and other wild animals follow the rainy seasons in Africa to find green grass. Whales migrate to warmer southern waters off the coast of Mexico to requite birth to babies because they could non survive in the cold waters of the Arctic Sea.

Some mammals hibernate because they cannot notice plenty nutrient to survive. Their body temperature falls, heartbeat and animate become slower. During this period hibernating mammals do not eat. They live from the fat of their bodies. Bats, squirrels and other rodents hibernate.

Mammals defend themselves from attackers in many ways. Hoofed mammals can run quickly in order to get food or escape. Squirrels rush into copse to hide. Some animals have special features that protect them from enemies. Skunks spray a bad smelling liquid to go on off attackers. The fur of mammals sometimes changes  with its surround. Arctic foxes, for case, are brown in summer and in the wintertime their coats plough white.

History of mammals

The showtime mammals probably evolved from reptiles almost 200 meg years ago during the Mesozoic period. They were rather small in a time when dinosaurs ruled the lands. When the dinosaurs died out well-nigh 65 1000000 years ago mammals became the dominant state animals. Many mammals became extinct during the Water ice Age , which ended thousands of years ago.

Today, some species are in constant danger of becoming extinct considering they are hunted by humans. Hunters and poachers earn money by selling fur, tusks and other parts of mammals. Larger wild fauna are often brought to zoos where they are protected.
