“…One of the most remarkable plant-animal seed dispersal systems on the African continent is that which has evolved between Cucumis humifructus, a rare annual member of the cucumber family (Cucurbitaceae) that fruits underground, a phenomenon known as geocarpy, and the aardvark (Orycteropus afer), only living member of the mammalian order Tubulidentata (Hollmann et al, 1995). Although the cucumber is dependant on the aardvark for survival, the aardvark is not at all dependent on the cucumber as it feeds almost exclusively on ants and termites (Taylor et al, 2002).…”
