In animals, infanticide involves the killing of young offspring by a mature animal of its own species, and is studied in zoology, specifically in the field of ethology. Ovicide is the analogous destruction of eggs. Although human infanticide has been widely studied, the practice has been observed in many other species throughout the animal kingdom. These include microscopic rotifers, insects, fish, amphibians, birds and mammals. Infanticide can be practiced by both males and females. Infanticide caused by sexual conflict has the general theme of the killer often male becoming the new sexual partner of the victim's parent which would otherwise be unavailable to it. This represents a gain in fitness by the killer, and a loss in fitness by the parents of the offspring killed. This is a type of evolutionary struggle between the two sexes, in which the victim sex may have its own counter-adaptations which reduce the success of this practice. It may also occur for other reasons, such as the struggle for food between females. In this case individuals may even kill closely related offspring.
