is a violet-cream dorid blotched with violet-brown and flecked
with white. It is superficially similar to Discodoris
differs from that species in having smaller lateral brown patches and
in having smooth, somewhat elongate papillae that are uniform in size.
Maui, unidentified discodorid #5
rare nocturnal dorid. The one animal we've seen, personally, was found in
tide pool at a moderately exposed rocky site. When resting during the
day, it contracted to only 25 mm in length and became very firm to
the touch. When active at night, it stretched to 45 mm and was much
softer. When disturbed, it flattened its mantle and swam in a manner
reminiscent of Hexabranchus.
Unlike Discodoris lilacina,
it didn't autotomize portions of its mantle even during extensive
handling. It laid a
cream egg mass with a ruffled edge. The second Maui animal was found in a similar habitat.

Taxonomic notes: This species may be a Sebadoris. But, it probably isn't Sebadoris nubilosa since
it doesn't autotomize portions of its mantle, has shorter papillae and
doesn't secrete copious mucus (traits listed for the latter species in
Kay, 1979). It's possible that it might fall within the range of
variation of Sebadoris fragilis but that species seems to have more pointed and more irregular papillae. It was first
recorded in Hawaii from Napili Bay, Maui by CP on Sept. 13, 1995.
