Aplysia cervina
(Dall & Stimpson, 1901)

Superfamily: APLYSIOIDEA
Family: Aplysiidae


West Atlantic, from southern USA to Brazil.


Locality: Estuary, Ceará State, Northeast Brazil, Atlantic Ocean, 25 January 2007, sand bank during the low tide. Length: 60 mm.  Lower photo showing colour pattern on parapodia. Photographer: Carlos Meirelles.

Note added 9 Feb 2007: see message #19409 showing this is a colour form of Aplysia brasiliana. _______________

Animal is a dull, translucent yellowish green with a reticulate pattern of thin black lines. Scattered  over the body and parapodia are a variable number of relatively large roundish black spots [10-60 on each side], and many smaller whitish spots, which appear to be glandular. The parapodia are joined very low posteriorly, and the rhinophores are relatively large with a split almost to their base.

This species is either relatively rare, or lives in a rarely visited ecosystem, because the few confirmed reports of this species are based on a single specimen or very few individuals.
