Distinct signs of sexual dimorphism are seen in the antelope. The male is considerably larger than the female. The females, as well as juveniles, have a rufous coat, whereas the males become yellowish grey or darker after the age of 2 years. The male has a prominent black crest of hair on the neck, but this feature is not well-developed in the female. One long white stripe runs along the back, with 11–14 white stripes branching towards the sides. The chest has a central black stripe, and no throat beard is present. A black stripe runs from each eye to the nose and a white one from each eye to the centre of the dark face. A chevron is present between the eyes. The area around the lips is white, the throat has white patches, and two white spots appear on each side of the lower jaw. The underparts are completely white, while the slender legs are tawny and have black and white patches. The lesser kudu is characterised by large, rounded ears. Its tracks are similar to the greater kudu's. Females have four teats. The average lifespan is 10 years in the wild, and 15 years in captivity.
