In rabbits, which gender typically has the dewlap?

The dewlap is a prominent flap of skin that is typically found in female rabbits. It is more pronounced in adult females, especially those that are mature and capable of breeding. The dewlap serves a few important purposes; it helps to regulate the rabbit's body temperature and also plays a role in maternal behavior during the nesting process.

In contrast, males do not usually develop a dewlap, and juvenile rabbits of both genders typically do not exhibit this feature until they reach sexual maturity. While all rabbits can exhibit various physical traits as they mature, the dewlap is a distinct characteristic associated specifically with adult females. This understanding highlights the differences in rabbit anatomy and provides insight into their biological functions related to reproduction and thermoregulation.
