Fig. 11

Schematic drawings of muscles of the opisthosomal chaetae in the competent larva of Siboglinum fiordicum. The scheme is based on the CLSM data. The ventral view of the level of the opisthosomal chaetae from the inside of the larva. Longitudinal muscles are shown in blue, circular muscles are in red, chaetae—in yellow. co—opisthosomal chaetae; mcch1-3—circular muscles of the chaetal apparatus, mlch1-10—longitudinal muscles of the chaetal apparatus, mls—longitudinal muscles of the first septum, mvvl—ventral component of the ventrolateral longitudinal muscle strand, moc1—the first circular muscle bundles in the opisthosoma, mv—ventral longitudinal strand
