What distinctive skin/hair feature is often present and more developed in female warthogs (sows)?
Answer
A prominent dewlap, which is a fold of skin hanging from the lower jaw and throat
Warthogs have sparse, coarse hair covering their bodies, ranging in color from greyish-brown to blackish-grey. While both sexes possess a mane running down the back, which is generally longer and stands erect in males when agitated, females possess another distinctive feature related to skin folds. Sows often develop a prominent dewlap, characterized as a fold of skin hanging down from the lower jaw area and throat. This feature is typically absent or far less developed in the males of the species.
