Male and female reproductive systems of the spotted hyena. In mammals, all intact developmentally typical males have a penis, but the clitoris in the females of the following species is sufficiently enlarged that it is usually termed a pseudo-penis: spotted hyena, [1] [2] juvenile fossa, [3] binturong, [4] lemur [5] and spider monkey.
Sexual mimicry can play a role in the development of a species' social system. Perhaps the most extreme example of this can be seen in the spotted hyena, Crocuta crocuta. [1] Female hyenas of all ages possess pseudomasculinized genitalia, including a pseudopenis formed from the clitoris, and a false scrotum formed from the labia.
The pseudo-penis and pseudo-scrotum, which are actually a masculinized vulva, closely resemble the male hyena's genitalia, but can be distinguished from the male by the female's greater thickness and more rounded glans. [23] Domestic cats have barbed penises, with about 120–150 one millimetre long backwards-pointing spines. [24]
The spotted hyena (Crocuta crocuta), also known as the laughing hyena, [3] is a hyena species, currently classed as the sole extant member of the genus Crocuta, native to sub-Saharan Africa. It is listed as being of least concern by the IUCN due to its widespread range and large numbers estimated between 27,000 and 47,000 individuals. [ 1 ]
The bulk of the NatGeo episode follows a pack of hyenas and a pride of lions, both with female leaders. The story of the hyenas is one of a transfer of power from one matriarch to another ...
A female spotted hyena's apparent penis is in fact an enlarged clitoris, which contains an external birth canal. [ 29 ] [ 30 ] It can be difficult to determine the sex of spotted hyenas until sexual maturity , when they may become pregnant.

The tail is short and the terminal hairs do not descend below the achilles tendon. [16] The female striped hyena's genitalia are transiently masculinized, [17] although it lacks the enlarged clitoris and false scrotal sack noted in the female genitalia of the spotted hyena. [18] The female has 3 pairs of nipples. [19]
