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]
Illegal hunting is a major conservation concern in many areas, along with natural threats posed by main predators (which include lions, leopards, African hunting dogs, cheetahs and hyenas). Where the black and blue wildebeest share a common range, the two can hybridise, and this is regarded as a potential threat to the black wildebeest. [26]
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 yellow-spotted tree frog is pale green with bronze patches that highlight dark spots. It has entirely webbed toes and is set apart from other frogs by the cream markings on its thighs.

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.
