This is an example
of a nudibranch that does not advertise itself with
bright colors-- instead it uses protective coloration to
disguise itself on the reef by blending in with its
background. This particular specimen is only about 1/2
inch in length.
Special thanks to Mike Miller
for his help with recognizing this unknown nudibranch, a
type of tritoniid
consistent with one he has seen and with an identical
nudibranch pictured in Sea
Slugs of Western Australia by Fred E. Wells
and Clayton W. Bryce.
Update 3/19/97: This specimen closely resembles two
undescribed species labeled Marionia sp.
in the book Nudibranchs
of Southern Africa by Terry Gosliner,
especially the second photo (sp. 2), which has visible
blue spots, similar to the photo in Clayton Bryce's book.
Identification: unknown; tentatively, Marionia
