Summary of regionalized SMP expression during larval shell development in Crepidula atrasolea. Summary table showing the lineage-restriction of each SMP, the best blast hit description, and shell field region(s) of expression (A). Circles in (A) indicate presence or absence of expression in the outer edge (outer Sf), inner edge (inner Sf), and/or the broader shell field (broad Sf). Half circles indicate presence of expression in one stage (late organogenesis or veliger) but not both. Cartoons depicting 5 different SMP expression patterns within the shell field of organogenesis and veliger stage C. atrasolea embryos (B). The SMPs are color coded in (A) based on their expression patterns shown in (B). Cartoons showing regionalization of the shell field into 3 potential zones of biomineralization in late organogenesis and veliger stage C. atrasolea embryo (C). These zones are highlighted in different colors: outer shell field edge in dark blue, inner shell field edge in light blue, and broader shell field in dark gray (C)
