There are three species of hyena— doglike carnivores found in Asia and Africa. Actually more closely related to cats than to dogs, hyenas have coarse fur, four toes on each foot, long forelegs, claws that do not retract, and enormously strong jaws and teeth. They live alone or in packs and may be active by night or day. Hyenas are noted for scavenging but will also attack live prey. The spotted, or laughing, hyena, whose calls alternately resemble wailing and maniacal laughter, ranges through much of sub-Saharan Africa. Yellowish or grayish with dark spots, it is about 6½ ft (1.8 m) long, including the 12-in (30-cm) tail, and weighs up to 175 lb (80 kg). The hyena has been known to attack people and even to carry off young children.
