Animals in Danger |
All Animals have different senses. They can see, hear, taste, smell and feel.
Note: Some male insects can recognize their females by their smell. For example, silkworm.
Dogs mark out their own area on the road. They can make out if another dog has come into their area by the smell of its urine or potty (latrine).
This special sense of smell of dogs is used by humans in the following ways:
Note: Is a smell ‘good’ or ‘bad’ for everyone in the same way?
It depends on how a person feels or thinks about a particular smell.
An eagle in the sky can see a roti on the ground from a distance of one and a half to two kms
Animals cannot see as many colours as we can. It is believed that animals that are awake in the daytime can see some colours. Those animals that are awake at night can see things only in black and white colours.

Some animals go into a long, deep sleep in certain seasons. Then they are not seen for many months. For example, lizards are not seen during the cold season. They stay awake almost during the entire day in winters.
Sloth looks like a bear but is not. It spends almost 17 hours a day sleeping while hanging upside down on a tree branch. The sloth eats the leaves of the same tree on which it lives. When it has eaten enough leaves from that tree, it moves to the nearby tree.
Sloths live for about 40 years and in that time they move around only eight trees. Once a week it comes down from the tree to relieve itself.
Sleeping time of different animals:
The tiger is one of the most alert animals.
People who kill animals are called Hunters and Poachers.
The number of tigers and many other animals in our country is reducing. There is a danger that some of them will soon disappear. To protect the animals, our government has made some forests as Protected Areas. Examples, Jim Corbett National Park in Uttarakhand and ‘Ghana’ in Bharatpur district of Rajasthan. In these areas nobody can hunt animals or destroy the jungle.
