Reproductive biology

Copepods have separate sexes, and mating behavior typically involves chemical signalling between the sexes. Females release pheromones, which provide information concerning her species identity as well as her state of sexual receptivity. Males home in on these pheromonal trails in a variety of ways. Copulation results in the transfer of a single or a pair of chitinous packets of sperm (spermatophores) onto the female genital region, and these usually discharge their contents into storage organs (seminal receptacles) inside the female.
