Cuthona pinnifera (Baba, 1949)
|Maximum size: 7 mm (Gosliner, 1979).
aeolid has annulate rhinophores similar to those of Cuthona sp. #22
but has fewer and thicker cerata. White pigment is concentrated in
well-defined patches on the central notum and cerata. The cephalic
tentacles have solid white
tips and the orange basal spots on the cerata appear more dorsal than central
(unlike those of Cuthona sp. #22).
Cuthona pinnifera is
a rare species known on Maui from only four animals found in moderately
moderately exposed rocky habitats at depths of < 1 to 1.5 m (< 3
to 5 ft). One found on Oahu in 1973 by Terry Gosliner was in a
highly protected to protected area (Kaneohe Bay). Gosliner (1979) and
Kay (1979) reported that the Kaneohe Bay animal was found in association
with the hydroid Halopteris diaphana.
Maui and Oahu: also found in Japan and French Polynesia.
It was first recorded in Hawaii from Kaneohe Bay, Oahu by Terry Gosliner in Aug. 1973.
