Mating between hyenas involves a number of short copulations with brief intervals, unlike canids, who generally engage in a single, drawn out copulation. Spotted hyena cubs are born almost fully developed, with their eyes open and erupting incisors and canines, though lacking adult markings. In contrast, striped hyena cubs are born with adult markings, closed eyes and small ears. Hyenas do not regurgitate food for their young and male spotted hyenas play no part in raising their cubs, though male striped hyenas do so.
