Moller, O. S., Olesen, J. and Hoeg, J. T. 2003. SEM studies on the early larval development of Tr iops cancriformis (Bosc) (Crustacea: Branchiopoda, Notostraca). — Acta Zoologica (Stockholm) 84 : 267-284 We investigated early larval development in the notostracan Tr iops cancriformis (Bosc, 1801-1802) raised from dried cysts under laboratory conditions. We document the five earliest stages using scanning electron microscopy. The stage I larva is a typical nauplius, lecithotropic and without trunk limbs. The stage II larva is feeding and has trunk limb precursors and a larger carapace. Stage III larvae have larger trunk limbs and a more adult shape. Stage IV larvae have well developed trunk limbs, and stage V larvae show atrophy of the antennae. We describe the ontogeny of selected features such as trunk limbs and carapace, discuss ontogeny and homologization of head appendages, follow the develop- ment of the feeding mechanism, and discuss trunk limb ontogeny.
