Paternity assurance in female snow crab under controlled multiple mating
Sperm competition is an important feature of the reproductive biology of numerous species. Among taxa in which females are polygamous and have sperm storage organs (i.e. spermathecae), mechanisms of sperm competition often favour single paternity and may fall into two broad cat egor ies , cal l ed s...
