Abstract
Summary The megalopal and first three juvenile stages of Lithodes santolla (Molina, 1782) are described in detail and illustrated, and ancillary information on carapacial spines and abdominal plate development in juvenile stages four and five are provided. Particular emphasis has been placed on the morphological changes occurring in the abdominal tergites and to the reduction and loss of uropods andpleopods. Additionally, variations in zoeal morphology from that described in an earlier study are noted. Simplification of the mandible, retarded development in the maxillule, and setal reduction on the maxilla during the three zoeal stages may be a function of the lecithotrophy of these larvae.
