Facelina sp. #4
Maximum size: 14 mm.
Identification:
Facelina sp. #4 is a distinctive aeolid with widely-spaced clusters of cerata. The
cerata have orange tips and yellow-white subapical bands. The bases are
translucent and variable in color, presumably due to the contents of
the digestive gland. There are prominent cnidosacs in their tips. (see photo) The cephalic tentacles have white tips and the
orange rhinophores have a white subapical band. The sides of the body
are marked with white and orange "lozenges" between the clusters of
cerata.
Natural history:
This appears to be
a rare species with the few known
animals found under ledges at 5-14 m (16-52 ft) in exposed to highly
exposed rocky areas (although it may be more common on Oahu).
Distribution:
Big Island, Oahu, Kauai and Niihau: also known from Kwajalein.
Taxonomic notes: It is illustrated in Bertsch and Johnson, 1981 as an
unidentified aeolid (p. 103, top photo). It was first recorded in
Hawaii
at Pupukea, Oahu by Scott Johnson on July 9,
1979.
