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 spotted hyena is very vocal, producing a number of different sounds consisting of whoops, grunts, groans, lows, giggles, yells, growls, laughs and whines. [47] The striped hyena is comparatively silent, its vocalizations being limited to a chattering laugh and howling. [48] Whoop of a spotted hyena in Umfolosi Game Park, South Africa.
It is still unclear whether the genus evolved in Africa or Asia, although the oldest known fossils are from Africa and dated to about 3.8 mya. [1] The earliest remains from Asia currently attributed to the genus is Crocuta honanensis from the Early Pleistocene of China dating to around 2.5-2.2 million years ago, but its relationship to the living spotted hyena is ambiguous.
The main predator of the calves is the spotted hyena. The calving peak period lasts for 2–3 weeks, and in small subpopulations and isolated groups, mortality of calves may be as high as 50%. However, in larger aggregations, or small groups living near large herds, mortality rates may be under 20%. [59]
Other bone remains came from woolly rhinos, yaks, small mammals like marmots, birds, and even from the spotted hyena, a large carnivore that prowled the region called the Ganjia Basin.
A 2024 study of a cave hyena genome from Sicily found that as with the 2020 study, there was strong genetic separation between Eurasian cave and African spotted hyenas, but unlike the 2020 study, there was no robust support for a basal split between East Asian/Siberian and European cave hyenas, with the Sicilian cave hyena found to be the ...
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).
