Populations are mostly parthenogenetic and composed almost entirely of hermophrodites. Males are extremely rare, arising only when physical conditions become unfavorable. The eggs undergo direct development in the brood chamber of the female and hatch as miniature replicas of the adults instead of the nauplius larva that is typical of other conchostracans.
