FIGURE 3. Embryonic period III in: A, Leurocyclus tuberculosus: it can observed the synchronization in the development (scale bar: 200 µm), B, L. tuberculosus: the outlines of the optic lobe can be clearly discerned (scale bar: 200 µm) and C, Libinia spinosa: the outlines of the optic lobe and the appendage can be clearly discerned (scale bar: 150 µm). D, Detail of L. spinosa: antennula and antenna (scale bar: 50 µm). E, Detail of L. tuberculosus: telson (scale bar: 50 µm). F, Detail of L. spinosa: telson (scale bar: 50 µm). Ab, abdomen; Annt, antennula; Ant, antenna; E, embryo; MI, maxilliped I; MII, maxilliped II; MA, mouth appendages; O, optic lobe; T, telson; Y, yolk.
