The red-flanked duiker (Cephalophus rufilatus) is a tiny antelope found in western and central Africa.
Red-flanked duikers grow to almost 15 in (35 cm) in height and weigh up to 31 lb (12 kg). They have russet coats, with black legs and backs, and white underbellies. They feed on leaves, fallen fruits, seeds, flowers, and sometimes small birds or other small animals. They have lifespans of 10–15 years in captivity.
The wild population is estimated at 170,000 individuals.
