Topi (Damaliscus lunatus), commonly known as tsessebe or sassaby, is one of Africa’s most numerous and widely distributed antelopes. It belongs to the Alcelaphini tribe (family Bovidae), which also contains the blesbok, hartebeest, and wildebeest. Damaliscus lunatus is known in East Africa as the topi and in Southern Africa as the sassaby or tsessebe. The topi has a broad geographic range and a spotty distribution. This is because particular grasses in desert and savanna biomes have specialized. Humans have further separated their populations via hunting and habitat encroachment.

Benin, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Ethiopia, Gambia, Ghana, Guinea-Bissau, Kenya, Mali, Mauritania, Niger, Nigeria, Rwanda, Senegal, Somalia, Sudan, Tanzania, Togo, and Uganda have all been found to have topi. Burundi, Gambia, Guinea-Bissau, Mali, Mauritania, and Senegal have all declared the species extinct. Topi prefer grassland settings that range from treeless plains to moderate woods.
The topi has one of the most complex social and breeding systems of any antelope. From permanent small herds to massive migratory aggregations, and from enormous individual territories to breeding arenas, or leks, where males crowd together and compete to inseminate females, social systems vary greatly.

Topi: Species Profile



SCIENTIFIC NAME: Damaliscus lunatus

TYPE: Mammal

FOOD: Topis are herbivores and primarily graze on grasses. They have a preference for fresh, green vegetation, but can also consume dry grass during times of scarcity. They are well adapted to feeding on tall, coarse grasses.

These expansive landscapes provide an abundance of nutritious grasses, which form the primary food source for Topis.

B. Preference for Water:

Topis are particularly drawn to areas near water sources, such as rivers, lakes, and marshes. These habitats not only provide drinking water but also support the growth of lush vegetation, which attracts herbivores like the Topi.

Social Behavior:

The Topi, scientifically known as Damaliscus lunatus, is a species of antelope found in the grasslands of Eastern Africa. Here are some key behaviors and characteristics of the Topi:

1. Social Structure: Topis are highly social animals and form herds of varying sizes. These herds can range from a few individuals to larger groups consisting of hundreds or even thousands of individuals. Within the herd, there is a hierarchical structure, with dominant males establishing territories and mating with multiple females.

2. Territorial Behavior: Male Topis exhibit territorial behavior, marking and defending their territories against rival males. They use scent markings from glands located near their eyes, known as preorbital glands, to communicate their presence and dominance to other males. Territory disputes between males can lead to aggressive interactions, including ritualized fights where they lock horns and push against each other.

3. Mating and Breeding: During the breeding season, which usually coincides with the rainy season, dominant males gather and establish territories known as leks. They engage in impressive displays to attract females, including showcasing their strength, agility, and the size of their horns. Females select mates based on these displays and usually give birth to a single calf after a gestation period of around 8 months.

4. Grazing Behavior: Topis are herbivores, primarily feeding on grasses. They are well adapted to grazing in open grasslands and have specialized teeth and jaws for efficiently cropping grass. They move in a steady, slow manner while grazing, often keeping their heads low to the ground to reach the tender shoots of grass.

5. Vigilance and Predation: Being prey animals, Topis are constantly vigilant for potential predators. They have excellent eyesight and hearing, allowing them to detect the presence of predators from a distance. When a threat is spotted, they will alert the herd by emitting alarm calls and taking evasive action. Their agility and speed enable them to flee from predators, including lions, hyenas, and cheetahs.

6. Seasonal Movements: Topis exhibit some seasonal movements, particularly in response to changing patterns of rainfall and availability of food. They may undertake migrations in search of greener pastures and water sources during the dry season. These movements are essential for their survival and help them maximize their access to resources.

The behavior of Topis reflects their adaptation to life in the grasslands of Eastern Africa. Their social structure, territorial behavior, grazing habits, and vigilant nature contribute to their survival in their natural habitat.
