is a moderately common dorid that may be found resting under ledges or
on shaded cliffs at depths of 3-24 m (10-80 ft). It occurs at

referred to as "Fellow's nudibranch" in Hoover, 1998 & 2006 as well as the "snowball sea slug" in Hoover, 1997. It was

It was named for David Fellows who collected the first specimens from
Pupukea, Oahu in July, 1965 (Kay & Young, 1969).
