|Maximum size: 34 mm.
has a translucent-gray body elaborately decorated with
orange and black. Its long velar appendages are densely papillate and
its body has a gelatinous texture.
Polycera abei is a
sporadically common diurnal species found on silty sand at 8-11 m
(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.
Maui: widely distributed in the Indo-Pacific. (Note 2)

Observations and comments:
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
There's some chance that this name has been used for animals
representing more than one species. Hawaiian animals seem close to those
illustrated as "Polycera sp. 2" on Robert Bolland's Okinawa site.
