We find animals everywhere-in the deepest oceans,the hottest deserts and even in very cold places like the mountains or the articles. The surroundings is which an animal lives are called its habitat.The ability to adjust the once surroundings is called adaption. Like plants,animals also need a habitat that that must meet their basic needs of food ,shelter,water and proper temperature. An animal may die if its habitat changes and a new place does not provide for its basic needs.
Habitat of animals
Animals adapt to the environment or their habitat in order to survive. The earth has many places such as the Cold Mountains, Thick forest, salty oceans, etc. These serve as habitats for different animals.
Observe these pictures to identify the habitat.
From these pictures you can see that we can classify animals according to their habitats they live in, such as terrestrial animals, aquatic animals, arboreal animals, aerial animals, etc.let us learn more about adapation in these animals.
Adapation in Terrestrial Animals
Terrestrial animals like the lion,cow and deer live on land. They breathe through their lungs.They have sense organs and well developed nervous system. They have strong muscular legs to walk and run fast in order to escape from animals trying to attack them.
Animals like polar bears,which live in very cold regions have thick fur to protect then from the cold. a thick fur of the fat under their skin keeps them warm and also helps them get through the winters when they do not find food .
Some animals like lizards, bears, snakes and dormouse sleep for several months in winters when it becomes very cold. this long winter sleep is called hibernation.they do this to protect themselves from the extreme weather.

animals like camels, which live in hot deserts have thick skins that protect them from the sun. They store fat in their hump abd water in their stomach, they have the ability to minimize their water loss. They have three eyelids. two of the eyelids have long eyelashes that prevent sand from getting into heir eyes. The third eyelid allows the camels to see even when it is closed. This adaption is helpful during desert storms. all these adaptions help the camel to survive in the desert.
Adaptation in Aquatic Animals
Aquatic animals live in water. Different types of fish, crabs, whales, dolphins and seals are examples of aqatic animals. These animals have specific adaptions which help them to survive in their habitat.
Fish breathe with the help of gills and move with the help of fins. The stream-lined shape of their bodies help the fish to cut through the water and swim fast. The hard skin and scales on their body prevent water from entering into it.
Water birds like herons have long legs which allow them to stand and walk in water. They also have a long pointed beak to catch their food with. Ducks have webbed feet that help them to swim.
Whales and dolphins are mammals that live in water. They breathe with the help of their lungs. They, therefore, keep coming up to the surface of water to inhale air.
Adapatation in Amphibians
Some animals like frogs, toads and salamanders are adapted to live both on land and in water. Such animals are called amphibans. They breathe with the help of their lungs when on land and through their soft skin when in water. They have legs that help them to walk on land and swim in water.
Adapation in Arboreal Animals
Arboreal animals like monkeys, squirrels and lizards spend most of their time on trees. They have strong arms and legs with well-developed claws to climb trees and cling to the branches. The long mascular tail of a monkey helps it to swing from one branch to the other. Some animals like lizards have plates which do not let them slip and also protect their bodies from getting hurt.
Adapation in Aerial Animals
Aerial animals like birds and insects are able to fly and spend much if their time in the air with the helpof their wings. The body of the bird is covered with feathers. Their bones are light and hollow, which make it easy for them to fly.their streamlined body helps them to cut through the air easily. Insects have light bones and wings which help them to fly.
Some birds like the Siberian crane and the atctic tern, which live in very cold places, cannot survive the cold winter in these places. Therefore, to escape the cold months, they fly thousands of kilometres to warmer places to find food, shelter and also to breed. They go back to their old when the winter end. This mass movement of birds from colder regions to warmer places every year is called migration.
