Hibernation
1. Finding food in winter is difficult for most animals when various sources of food like insects
or plants are not available in plenty. It is during this time, most animals cope with the lack
of food by hibernating.
2. Hibernation is that deep sleep taken by certain animals that helps them not to waste
energy so that they can survive the winter without much food. An animal’s body
temperature falls during hibernation. The heartbeat and breathing slows down so it saves
energy.
3. Hibernating animals prepare for winter by eating more food than they need. They store the
food as body fat. This fat is used as energy when they sleep. The fat is formed in patches
near the animal’s brain, heart and lungs. These patches send a quick boost of energy to
warm these organs when the animal’s wake up.
4. Fish, bear, lizard, frogs and turtles are a few examples of hibernating animals. They have
no means to stay warm in the winter season. They take shelter under logs, stones and piles
of dry leaves. The animals move downwards to the bottom of lakes and ponds. Some even
burrow into the mud to avoid the cold winter. Insects can hibernates as well. To keep
warm, these insects find holes underground, inside trees or fallen logs. Some hibernating
animals appear to be dead during this time.
5. Certain animals might wake from their sleep and shiver in order to warm themselves when
the temperature drops really low. Some hibernating animals might wake up for a little time
to use their ‘toilet rooms’. They might eat a little food if they can find any.
