Many branchiopods are morphologically relatively primitive and evade com-petition from more advanced forms by physiological adaptations which enable them to survive in extreme environments. The most recently evolved group of branchiopods, the Cladocera, or water fleas, have specialisation of morphology and reproduction which have enabled them to …The brine shrimp Artemia exhibits two reproductive modes: 1) oviparity, producing diapause embryos; and 2) ovoviviparity, producing free-swimming nauplii. Previous studies have suggested the existence of a critical stage that determines the reproductive mode. Physicochemical factors, such as photoperiod, temperature, and salinity, have been suggested to irreversibly affect the reproductive ...The origin of branchiopods is estimated dating back to the Cambrian 2,3 and the class is currently recognized to include at least 1200 aquatic species (including brine shrimps, tadpole shrimps ...

This phylogeny and gene order showed two distinct groups: Anostraca (Artemia, Phallocryptus and Streptocephalus) and a second group formed by L. lenticularis, …

Since most branchiopods produce dormant propagules directly (Cáceres, 1997), the better strategy is to mature and reproduce as soon as possible before the hydroperiod ends (Hildrew, 1985; Brendonck et al., 2000).
