Thermoregulation in Camel

Camel is a desert mammal. It is called the ship of the desert as it is well adapted to live in hot sand of deserts. The camel has the following adaptations for desert life:

1. Camel is an eurythermal animals as it has the ability to tolerate wide variations in temperature. 2. Camel is a warm blooded animal (homeotherm) as it can keep its body temperature well above the ambient temperature as other mammals and birds. 3. Camel is also a hypothermic animal as it can keep its body temperature abnormally low during night. 4. Camel is an endothermic animal as it has the ability to generate temperature from the body. 5. The camel is a temporal heterothermic animal as their body temperature is very high during hot day and very low during cool night. It cannot maintain the body temperature within a narrow range. It absorbs heat and allows its body temperature to go high up 58°C*, on a hot day. Similarly, during night, it allows its body temperature to drop several degrees below normal. 6. Camel is a large animal. It cannot hide into a burrow like small animals during hot days. 7. As it is a large animal, its surface/mass ratio is low and heat capacity is high. 8. Camel has a thick pelagic that helps insulate from external heat. 9.Low surface area and thick pelagic retard the absorption of heat from the surrounding. 10. Camel has high specific heat of tissue water.This helps camel to absorb relatively large quantities of heat for a given rise in body temperature. 11. The dehydrated camel can also tolerate an elevation of its core temperature by several degrees, further increasing its heat absorbing capacity. 12. The camel allows its body temperature to go high up without sweating. This prevents loss of water from the body. 13. Camels fur acts as an effective barrier to heat transfer. It helps conserve water and retard heating up of the body. 14. Camel drinks large quantity of water in a short time.15. The camel has long eyelashes that keep its eyes safe from wind borne sand. 16. It has muscular nostrils that it can completely or partially close at will.
