Skeletal anatomy of the zebrafish pectoral fin. a Skeletal anatomy of the zebrafish pectoral fin with Alizarin Red staining. The bottom box shows a magnified view of the upper whole pectoral fin skeleton in the inset. The scale bar indicates 1 mm. b, c Schematics of the fin rays and radials. Drawings in dark blue and pink indicate radials and fin rays, respectively. Each of the proximal radials (pr) and distal radials (dr) are indicated in c. dr5, and dr8 occasionally did not appear (asterisk)
