Unidentified
Discodorid #17
Maximum size: 12 mm.
Identification:
This
is
a gray-cream animal with small, irregularly-sized, conical tubercles.
The larger tubercles and
rhinophores are tipped with opaque white and the branchia are dusky-gray
with a few small white tips. Some tubercles may also have dusky-gray pigment. The rhinophore lamellae are asymmetrical
creating concave tips.
Natural history:
Unidentified discodorid
#17 is known from five animals found at exposed to highly
exposed sites. The two 2021 animals were found at less than 3m (10 ft) and 5-7 m (16-23 ft).
Distribution:
Oahu.
Taxonomic notes: We're leaving this species in the Discodoridae, for the time being, but the family is uncertain (it was
previously listed as "Unidentified Dorid #17" on our site and Sara suggested Doris sp. in the family Dorididae). It was first recorded
in Hawaii from
Makua, Oahu by Scott Johnson in
Sept. 1979.
