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.
Subordinate
female individuals
lick the clitoris of a higher-ranked
female as a clear sign of submission and obedience.
