Stripped Hyena, Hyaena hyaena, is a species of Hyena found in the Northeastern end of Nigeria, so named because of the black stripes on the sides of the pale grey or beige coat. It is like other hyenas dog-like in appearance, with powerful forequarters and a back that slopes down towards the bushy tail. Striped Hyenas have a body length of 110 cm a tail length of 20 cm and they weigh between 35 and 40 kg. They are grey or pale brown in color and have a mane on their neck and shoulders. This mane can be raised to make the hyena look quite large, and is used in displays against other striped hyenas. Unlike the highly social Spotted Hyena, they are mostly solitary. They are active at night and they spend their days sleeping in a burrow or cave. The subspecies barbara occurs in Nigeria.
