Phyllidia sp. #1
|Maximum size: 42 mm.
elongate-oval with three longitudinal ridges that may
be composed of either fused or discontinuous, simple tubercles.
background color is black and the tubercles are capped with dark yellow
ringed with blue-gray basally. Crescent-shaped blue-gray areas
containing black spots and yellow-capped tubercles are usually present
around the mantle margin. Rarely, the yellow caps may be largely absent. The rhinophores are yellow and the foot is
uniformly gray. It can be distinguished from the much more common Phyllidia
varicosa by the lack of a
dorsal anus, simple instead of compound tubercles, lack of a black
medial stripe on the ventral surface of the foot and the dark yellow
caps on it's tubercles. It can be
distinguished from Phyllidia exquisita by the lack of
a dorsal anus and marginal yellow line.
Phyllidia sp. #1 is
rarely found on rocky bottoms in moderately
exposed locations at depths of 6-24 m (20-79 ft). It may feed on a burnt-orange sponge.
Big Island, Maui, Molokai, Oahu and Kauai.
formerly placed in the genus Fryeria
due to its lack of a
dorsal anus. However Fryeria
has now be synonymized with Phyllidia.
