has a soft, translucent-white body with an opaque-white
submarginal band. The crenelate mantle
edge overhangs slightly and has a pale gold marginal line.
The rhinophores are black with thin blue-white vertical lines on their
faces. The branchial plumes are white basally and black distally (often
with a blue-white line on the outer face). It is sometimes confused with
fellowsi which is also
white with black gills and rhinophores. The latter species, however,
has a firm body and lacks the gold marginal line.
is rarely seen by divers on Maui but appears to be more common on Oahu.
It may be found under rocks or in the open in
rocky areas at moderately protected to exposed locations. It's been
recorded at depths of 5-20 m (16-65
ft) and vibrates its gills. It probably feeds on a cream sponge.
Big Island, Maui, Lanai, Oahu and Niihau: also known from Okinawa.
