Hyaena hyaena (Linnaeus, 1758).
A large animal about 103-109 cm head-and-body length; the short tail is 30 cm. The overall color is greyish-brown with broken transverse black stripes on the back and a marked black spinal crest. It is noticeably higher at the shoulder than at the rump and the head is massive. The hyaena inhabits desert areas bordering the Nile Valley, entering cultivated areas at night to feed and drink; it also dwells in remote areas with its den in rocky hills and crevices. It is a generally solitary, nocturnal scavenger; its food consists largely of carrion as well as gazelles, rodents, birds, and vegetable matter; it probably follows the camel caravans in anticipation of dead camels. Its powerful jaws and teeth allow it to crack the largest bones to get to the marrow within. One to six cubs are born after a gestation period of 88-92 days. In Egypt, the hyaena is widespread, especially in the Nile Valley. Worldwide, it ranges from India and Transcaucasia through the Middle East, North Africa, and parts of sub-Saharan Africa.
