Males in most hyena species are larger than females, [34] though the spotted hyena is an exception, as it is the female of the species that outweighs and dominates the male. Also, unlike other hyenas, the female spotted hyena's external genitalia closely resembles that of the male. [35]
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 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] Adult weight can range from 22 to 55 kg (49 to 121 lb), averaging at about 35 kg (77 lb).
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.
The juvenile female fossa's os clitoridis and pseudo-penis shrink as she grows, unlike that of other pseudo-penis species. [3] The mammalian pseudo-penis appears to be simply for display, though the spotted hyena is an exception: the female spotted hyena urinates, copulates, and gives birth through her pseudo-penis.
An average adult male weighs 40.2–43.7 kg (89–96 lb), while an average female weighs 37.7–40.2 kg (83–89 lb). [6] Brown hyenas have powerful jaws, and young animals can crack the leg bones of springboks in five minutes, though this ability deteriorates with age and dental wear. [7]
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.
