MyHC expression during muscle differentiation at stage 32 in Scyliorhinus canicula; cranial to the left. a The constrictores branchiales I-IV completely cover the branchial arches; deep branchial muscles cannot be identified. b The cucullaris muscle stretches dorsally to the branchial arches with dorsally attaching to the most caudal one. c The ventral aspect is almost completely covered by muscles. Deep branchial muscles, such as the coracobranchiales, are no longer visible. d Ventral view of pectoral region. The abductor and the adductor superficialis are expanded. Scale bar = 1 mm
