During the larval stages, decapod crustaceans live as planktons, with different morphological adaptations from the adults, which are usually benthic. The genus Lysmata is composed by shrimps from the infraorder Caridea and the Lysmatidae family and they are characterized by the diversity of lifestyles and behaviors they present. Although they have a large geographical distribution, there is still a lack of information about the first stages of life (larva) of their representatives, which could provide important characteristics to be used for phylogenetic analyze of the species. Since just a few species of Lysmata have their larval forms described, the purpose of this study is to describe and illustrate the morphology of the larval development stages of the species Lysmata ankeri, L. bahia and L. intermedia. The ovigerous females will be collected at the Couves Island, Ubatuba (São Paulo) and at the Port of Santos, Santos (São Paulo) and later will be transported to the laboratory where they will be kept until larvae hatch. The larvae will be individually raised and monitored daily to see mortality and the larval developmental stages. At each stage, ten larvae will be fixed (10% formalin and transferred to a mixture (1: 1) of 70% ethyl alcohol and glycerin) and subsequently dissected, and the morphology of each appendix will be illustrated and compared among the three species of this study and among some other species that were described before by other authors. Studies about larval development are important in order to obtain information on the morphological diversity of species, besides to contribute to the identification of the planktonic community organisms and to better understand the phylogenetic relationships among the species of the genus Lysmata. Those information can also serve as basis for the cultivation of these species in laboratory, since shrimps of the genus Lysmata are widely commercialized as ornamental organisms. (AU)
