Competition cum twins

Sperm competition , a special form of mating competition that occurs in sexual species when females accept multiple mating partners over a relatively short period of time. The potential for overlap between the sperm of different males within the female has resulted in a diversity of behavioral adaptations and bizarre strategies for maximizing paternity. Sperm competition is thought to be the primary reason why males offer nuptial gifts such as food to females or allow females to cannibalize them. Such nuptial gifts are best thought of as mating effort that is, effort directed at increasing the number of offspring a male sires , because they are usually not available at the time of birth or hatching to benefit the offspring sired by the male presenting the gift.
