Cannuel and Beninger (2006) demonstrated that the inner demibranchs of the gills develop earlier than the outer demibranchs. Plication of the gill is also attained relatively late in ontogeny. The gills of early juveniles of the species are thus structurally and functionally different from those of the adult.
