Definition
A dewlap is a flap of skin hanging from the neck or throat of some animals, including cattle, lizards, and certain birds π¦. It can serve various purposes, such as thermoregulation, display, or fat storage. In some species, the dewlap is more prominent in males and used for attracting mates. Think of it as a natural billboard for communication or a cooling fan. The size and function of the dewlap vary across species. It's an example of adaptation to specific environmental or social needs.
