(26-36 ft). (Note 1) It feeds on a small, brown,
sand-anchored bryozoan. Irregular cream egg masses are usually wrapped
around small sprigs of its host bryozoan in the field. Comparable
masses laid in dishes hatched in about four days in the laboratory.

Observations and comments:
Note
1: We saw many animals scattered
over the bottom in small aggregations of 3 to 10 during a series
of dives at Maalaea Bay
in April and May, 2008. However, we haven't seen the species before or
since.
Note 2:
There's some chance that this name has been used for animals
representing more than one species.
