FIGURE 51 in Molecular and morphological systematics of Elysia Risso, 1818 (Heterobranchia: Sacoglossa) from the Caribbean region

FIGURE 51. Elysia zuleicae, external morphology and egg masses from Discovery Bay, Jamaica (A; March 2006); Little San Salvador, Bahamas (B–D, F, H; July 2007); or Bocas del Toro, Panama (E, G; December 2004). All measurements give body length of specimens. A, Specimen (8 mm) with light-colored rhinophores, parapodial margin and tail. B, Side view of specimen (12 mm) with dark maroon rhinophores, marginal bands of purple and brown on dark green parapodia, and thin, dark-colored tail. C, Top view of same specimen, showing parapodial margin, short renopericardial extension, and head. D, Ventral view of foot. E, Dorsal view with parapodia open, showing renopericardial complex, dorsal vessel network, and white gametic vesicles. F, Light-colored specimen (8 mm) with black speckling inside parapodia and on dorsal vessels. G, Light-colored juvenile (3 mm) with parapodia held flat against the substrate. H, Dark-colored juvenile (3 mm) with black marginal line. I, Planktotrophic egg mass laid by specimen from Jamaica, showing white ECY ribbon intercalated among early-stage embryos. Field of view = 2.1 mm. J, Lecithotrophic egg mass laid by specimen from Plana Cays, Bahamas, showing thick white ECY ribbon on upper inside face of egg mass, and encapsulated veliger larvae. Field of view = 6.8 mm. K, Lecithotrophic egg mass laid by specimen from Sweetings Cay, Bahamas, showing remnants of white ECY ribbon intercalated among encapsulated late-stage veliger larvae, close to the point of hatching. Field of view = 2.1 mm.
