young, 2.5 mm
Chromodoris sp. #2
|Maximum size: 16 mm.
has a translucent white body decorated with varying amounts of
opaque white which can form either a reticulate pattern or be
concentrated and give the animal a more solid white appearance. In
either case, there are several medium-sized translucent spots on either
side of the mid-dorsal area and randomly shaped translucent areas just
inside the mantle margin and behind the rhinophores. The mantle margin
is sometimes edged in pale gold or pink and there are sometimes small
flecks on the notum. The rhinophores and gills range from translucent
white to light gold and the posterior portion of the foot extends well
beyond the margin of the notum.
Chromodoris sp. #2
is a rarely seen species found on rocky bottoms from
< 1 to 12
m (< 3 to 40
ft) in moderately protected to moderately exposed
locations. However, Scott Johnson reports
it to be fairly common at exposed to highly exposed sights on Oahu.
It's nocturnally active but may be found under rocks or in
caverns during the day. Scott Johnson also reports that a Hawaiian
animal laid a white, flattened spiral egg mass comprised of four whorls
that lacked extra-capsular yolk. (pers. com.) (Note 1)

animal on page 45) and was first recorded in Hawaii by Scott Johnson.

Observations and comments:
1: Egg masses that are flattened (i. e., composed of a
ribbon attached to the substrate by its side rather than its edge) and
that lack extra-capsular yolk are characteristic of the genus Chromodoris. This contrasts with the genus Goniobranchus
in which the ribbon is attached by its edge and extra-capsular yolk is
present. So, Scott's observation supports placing it in this genus.
