Perceived certainty of paternity is expected to influence a male’s behavior toward his offspring: if he is uncertain of his reproductive success with a current brood due to the presence of cuckolders, it may benefit him to invest instead in future reproduction. A decrease in perceived certainty of paternity incites filial cannibalism (the eating of one’s own offspring) in some teleost fishes that provide parental care; however, no work has demonstrated that cannibalism increases proportionately… Expand
