Camels, sand snake, Mongoose, Rats and Kangaroo are desert animals.

Inspire of scarcity of water and sad storms, some animals are able to live in such adverse conditions. Rainfall is short water called ``Oasis’’ are present at far distances.

 

Camel living in desert

1) The camel eats as much food as is available. Eg. Thorny shrubs, bushes and hay.

2) In the hump. The undigested food is stored in the form of fat. This fat is used in times of starvation. Digestion of fat releases water, which is utilized by the camel.

a) hair covers the body thickly

b) sweat pores are absent

c) urination is very less

4) protection form sand-storms

a) Nasal channels are narrow and locked well inside the nose, even though the nasal openings are wide. Thus this is considered as a good arrangement to prevent sand from entering the nose.

b) Sand may fall in their eyes. Therefore the eyes are covered and protected by the projection of eyebrows over the eyes. Why camel is called the `ship of the desert? ‘The camel walks and runs on the hot sand. The feet do to sink in to the sand. Why? On the hoofs there are thick and wide pads.

 

Polar animals

The Polar Regions are covered with ice .the water in ocean consists of big blocks of ice. Seals and fish are the animals living in the frozen water. The day and night is of 6 months duration in Polar Regions.

 

How do the polar animals like bear live in such cold regions?

a) Thick, white fur prevents loss of heat from the body and acts as an insulator.

b) Hairy feet prevent them from slipping on the ice. Webbed feet enable it to swim in water.

During unfavorable conditions the animals undergo winter sleep. During this period respiration and heart beat are slowed down and the stored fat is used as food. Thus, all animals modify their bodies and habits to adapt themselves to their environment.
