What defining physical marker, besides the hump, is characteristic of Zebu cattle?
Answer
A larger dewlap hanging from the neck
Zebu cattle possess several key physical features that distinguish them from *Bos taurus*. While the most prominent feature is the fatty hump over the shoulders, another essential morphological characteristic is the dewlap. The dewlap is described as the loose skin flap that hangs significantly from the neck area. This feature, along with their characteristic droopy ears, aids in increasing the overall surface area available for heat exchange, contributing to their superior resilience and thermoregulation capabilities in hot, humid tropical environments where survival demands efficient cooling mechanisms.
