Gymnodoris sp. #6

Maximum size: 14 mm (Kay,
1979).
Identification:
This is a small species that rarely exceeds 8 mm in length. It has a
cream body with orange spots. The rhinophores are rod-like when fully
extended and there is a white patch between the eye spots that connects
to irregular white patches near the gills. The rhinophores and gills
are usually tipped with orange. The rod-like rhinophores and less
prominent white pigment posterior to the gills distinguish it from
young Gymnodoris okinawae.
Natural history:
Gymnodoris sp. #6
is a moderately common species found in moderately exposed to exposed
rocky habitats and Halimeda kanaloana
beds from < 1 to 15 m (< 3 to 49 ft). It appears to feed on small
elysiids (Note 1). It lays a small, bright
orange egg mass that hatches in about eight days in the laboratory.
Distribution:
Maui and Oahu: widely distributed in the Indo-Pacific.
Taxonomic notes:
This is the species that Kay, 1979 lists as Gymnodoris plebeia (Bergh, 1877a).
It was first reported from Hawaii in Kay & Young, 1969.

Observations and comments:
Note
1: On Nov. 21, 1995 we observed one
regurgitate an unidentified Elysia.
Over the years, one each of three Elysia
spp (Elysia pusilla, Elysia sp. #2 and Elysia sp. #6) have "disappeared"
while held in dishes with this species. On Dec. 8, 2003, we
observed one eat an Elysia pusilla
engulfing it rapidly "on contact."
