Figure 6 in Development, phylogeny, and taxonomy of Bostrycapulus (Caenogastropoda: Calyptraeidae), an ancient cryptic radiation

Figure 6. Embryos of Bostrycapulus pritzkeri sp. nov. Note the distinctive granular shell sculpture and the absence of a distinct velum at all stages. A, excapsulated early stage embryos at the beginning of shell formation. Scale bar = 150 Mm. B, excapsulated embryos with welldeveloped shells showing granular shell sculpture and the small ridge of the velum at the base of the tentacle. Scale bar = 250 Mm. C, encapsulated embryos near hatching with fully developed shell and body pigmentation. Scale bar = 250 Mm.
