In the sand goby, sperm competition arises when parasitically spawning males enter nests and release sperm. Virtually all types of males spawn parasitically: nest-holding males with eggs, nest-holding males without eggs, males in breeding colouration without nests, and sneaker morph males without breeding coloration but with huge testis. They seem to use female behaviour as their prime cue for a parasitic spawning opportunity.
