Table 1 Myogenic cephalic and pectoral/pelvic fin development in Scyliorhinus canicula. Stages according to Ballard et al. [52]. Terminology and adult characteristics follows Ziermann et al. [18]. x = present (independent on status of differentiation); o = absent (or not stained); (number) = number of repetitive muscles (usually corresponding to branchial arches and counting from anterior to posterior). Orange box = dorsal constrictor of mandibular arch. Yellow box = constrictor hyoideus. Green box = only one abductor could be found in the S. canicula stages investigated here. (?) could not be observed because of overlying muscles. *Adult condition is from Squalus acanthias [18]
