The Lechwe conch (Kobus milk) is an African antelope specialized in humid environments such as floodplains and swamps, where its morphology is adapted to muddy conditions and waterlogged terrain. Its hind legs are longer than its front legs, giving it a forward-leaning posture that facilitates its movement in water. In addition, its fur contains sebaceous glands that secrete an oily substance, acting as a natural waterproofing agent. This antelope has a slender body, with marked sexual dimorphism: males have large, spiral, lyre-shaped horns, while females lack them. Its diet consists mainly of soft grasses and aquatic plants, making it a key species for the ecological balance of wetlands. It lives in areas where the water level varies seasonally, taking advantage of new vegetation after flooding. Its dependence on humid habitats limits its geographical distribution and makes it vulnerable to hydrological disturbances.

This antelope is social and gregarious, forming large herds, often composed of several hundred individuals. These herds are usually segregated by sex: single males form separate groups, while females gather with their young. During the breeding season, males congregate in display areas called "leks," where they compete for the attention of females through physical displays, dominant postures, and ritualized confrontations. It is not a migratory species, but does make seasonal movements to areas with better flooding or vegetation. It is diurnal, with greatest activity in the early morning and at dusk. When threatened, they tend to take refuge in the water, where they move with great agility, unlike their predators. Group cohesion and cooperative vigilance allow for early detection of danger, reducing mortality due to predation.

Listed as Near Threatened on the IUCN Red List due to the progressive deterioration of its natural habitats, its dependence on functional wetlands makes it extremely vulnerable to hydrological changes caused by dam construction, canalization, drainage for agricultural use, and alterations in seasonal flooding patterns. It also faces threats from poaching and competition with domestic livestock in unprotected areas. Although some populations, such as those in the Okavango Delta, remain stable, others have suffered considerable declines. Conservation programs exist in national parks and nature reserves, as well as captive breeding initiatives in international zoos. International trade is regulated under CITES Appendix II. Restoration of wetland ecosystems and sustainable water management are essential for the long-term survival of this species. Continued population monitoring is a priority to prevent its decline into higher-risk categories.
