How does the Zebu's dewlap aid in surviving high temperatures?
Answer
It increases the overall surface area available for heat radiation
The dewlap, which is a large fold of loose skin hanging from the neck of the Zebu, plays a crucial role in thermoregulation in hot climates. Along with the loose skin found over the rest of the body, this prominent feature significantly increases the total surface area available for the animal to radiate excess body heat into the environment. This physiological mechanism is vital for managing thermal load and preventing dangerous overheating when temperatures are soaring in tropical and subtropical environments.
