Abbreviations: C, labeled cilia; CB. ciliary bundles; CT, ciliary tuft; V, velar lobes. (A) Low-magnification image of a newly hatched, competent larva of Berghia verrucicomis in frontal view. The ciliary bundles of the five ampullary neurons lie beneath the ciliary tuft and between the velar lobes. (B) High-magnification image of the five ampullary neurons in a newly hatched, competent larva of B. verrucicomis.

Abbreviations: C, labeled cilia; CB. ciliary bundles; CT, ciliary tuft; V, velar lobes. (A) Low-magnification image of a newly hatched, competent larva of Berghia verrucicomis in frontal view. The ciliary bundles of the five ampullary neurons lie beneath the ciliary tuft and between the velar lobes. (B) High-magnification image of the five ampullary neurons in a newly hatched, competent larva of B. verrucicomis. Note the very long ampullary canals that are defined by the labeled cilia within. In some cases (, arrowhead) anti-tubulin labeling of the cilia suggests that more than one canal may arise from a single ampullary neuron. (C) The ciliary bundles of the five ampullary neurons in a newly hatched, near-competent larva of Phestilla sibogae. Note that the canals of the ampullary neurons appear to form two tight groups on the left and right sides of the ciliary tuft. (D) The five ciliary bundles of the ampullary neurons in a newly hatched planktotrophic larva of Melibe leonina. As indicated by very weak labeling, few cilia are present in the apical canals of this planktotrophic species at hatching. (E) High-magnification image of the five ciliary bundles in a 13-day-old larva of M. leonina (~19 days before competence; Bickell and Kempf. 1983). This larva is a little over halfway to metamorphic competence. As in B. verrucicomis, very long apical canals are revealed by labeling of cilia within. Also, as in B. verrucicornis. in some instances anti-tubulin labeling of the cilia suggests that more than one canal extends from a single ampullary neuron (arrowheads). (F) The ciliary bundles in a veliger-stage embryo of Phyllaplysia taylori. Only four ampullary neurons are present in encapsulated vehgers of this species.
