Alcelaphus buselaphus caama is a large African antelope of the family Bovidae, one of ten subspecies; it is sometimes treated as a separate species, A. caama. Commonly known as the red hartebeest, it is the most colorful hartebeest, with black markings contrasting against its white abdomen and behind. It has a longer face that other subspecies, with complex curving horns joined at the base.hartebeest. Encyclopædia Britannica Online. The average weight of a male is about 150 kg, and female is 120 kg. Their average shoulder height is 135 cm, and horns are 60 cm long. The life expectancy of a red hartebeest is around 19 years.Red Hartebeest . SMJ Safaris. 2012. Little sexual dimorphism is noted between males and females, showing no distinct identifiable physical features, but body size is slightly affected. Horn size, however, expresses more dimorphism between males and females, as males fight and defend themselves for sexual selection. Thus, male skull weight and circumference is slightly greater than that of the female.Capellini, I. (2007). "Dimorphism in the hartebeest.
