FIG. 5 in Regeneration in the dorids exemplified by Onchidoris muricata (Gastropoda, Nudibranchia)

FIG. 5. Rhinophore regeneration after removal of the apex and three rhinophore lamellae (light microscopy). A. Frontal section through the front of the body. Left – intact rhinophore, right – rhinophore 1 day after amputation of the apex and two rhinophore lamellae (1dpa). B. Regenerating rhinophore (1 dpa). The apical lamellae are everted. C. Top view of the rhinophores at 3 dpa. On the left – regenerating rhinophore, on the right – intact rhinophore. D. External morphology of the regenerating rhinophore at 3 dpa. E. Frontal section through the front of the body. Left – intact rhinophore, right – rhinophore 1 day after amputation of the apex and two rhinophore lamellae (5 dpa). F. Regenerating rhinophore (5 dpa). Apical lamellae return to normal position. G. Top view of the rhinophores 21 days after amputation. On the left – regenerating rhinophore, on the right – intact rhinophore. The formed tip of the rhinophore is visible. H. Regenerating rhinophore with internal spicules (21 dpa). Abbreviation: arl – apical rhinophore lamellae; arrh – apex of regenerating rhinophore; bc – buccal complex; irh – intact rhinophore; rl – rhinophore lamellae; rrh – regenerating rhinophore; rt – rhinotubercles; sp – spicule; spb – spicule of body; t – tubercle.
