Lizards are poikilothermal (cold-blooded) and their body temperature fluctuates with outside temperature. When it’s extremely cold, lizards face the danger of either their blood freezing up or their temperature dropping drastically, as a result of which they become immobile and can easily fall prey to enemies. Hence, lizards hibernate in cracks of walls or beneath the soil. During this period, their basal metabolic rate is greatly reduced.
- Since their prey – insects – go into hibernation, lizards also call it a day and hibernate.
- Because they go on winter vacation.
- Just as one cannot spot a politician during posts, elections.
