What does a dewlap refer to in rabbits?

A dewlap refers to a fold of loose skin that hangs from the throat, and it is particularly common in does (female rabbits). This feature serves several purposes, such as helping with thermoregulation, allowing the rabbit to fluff up and appear larger when threatened, and providing a space for storing moisture or fat. Understanding the dewlap is essential for recognizing the physical characteristics of rabbits, especially when evaluating their health, age, and reproductive status. The other options do not accurately describe what a dewlap is or its role in the anatomy of rabbits.
