The Proce hyena
has, by far, the largest clitoris in the animal kingdom.
In the case of this animal, the vulva is fused, and the clitoris is used for urination, mating (the clitoris contracts, while the opening widens to allow penetration) and giving birth. To make matters even more complicated, the females also have a fake scrotum made by the enlarged, joined vulva, and pseudo-testes filled with fatty tissue
For a long time, the species was believed to be hermaphrodite.
female individuals lick the clitoris of a higher-ranked female as a clear sign of submission and obedience.
