What feature on a rabbit is located under its chin?

The feature located under a rabbit's chin is known as the dewlap. This is a loose fold of skin that hangs down from the neck and is more prominent in female rabbits, especially those that are sexually mature or in breeding condition. The dewlap serves several purposes, including aiding in temperature regulation and providing a space for the rabbit to store fat, which can be especially important for energy reserves in females during breeding or nursing periods.

Understanding the dewlap's function is important for those involved in rabbit breeding and care, as it can indicate a rabbit's health and reproductive status. In contrast, the flank refers to the side of the rabbit's body, the saddle refers to the area on the back where the coat can change in color or texture, and the stifle is a joint in the hind leg, all of which do not have the same anatomical or functional relevance as the dewlap in relation to the rabbit's chin area.
