Rabbit
Dewlaps

A dewlap is a longitudinal flap of skin or similar flesh that hangs beneath the lower jaw or neck. It is a secondary sex characteristic in rabbits, caused by the presence of female sex hormones. They develop with puberty. A female rabbit who has been neutered before reaching sexual maturity will not develop a dewlap, and even if a doe is neutered after developing a dewlap, the dewlap will gradually disappear over several months. This also aligns with the results of injecting male rabbits with female sex hormones, specifically the ones from pregnant women's urine. The male rabbits developed dewlaps, which then gradually disappeared once administration had ceased. (This is not the process of the rabbit test, a common way to test for human female pregnancy in the 20th century; the pregnancy test involved dissecting female rabbits after injection with urine to see if their ovaries had enlarged.) While it is unclear exactly what function a dewlap performs, pregnant female rabbits will pluck fur from their dewlaps shortly before giving birth to line a nest for their young.
