Chromodoris(?) sp. #4
Maximum size: 15 mm.
Identification:
This
soft-bodied
species has a wide, slightly undulating
margin and low, but distinct, rounded pustules about 0.5 mm in diameter
covering its notum. Body color is translucent gray with opaque white
covering the visceral area. The white pustules are more concentrated
mid-dorsally giving the animal an overall white appearance. There is a
narrow yellow-green marginal line and a wide white submarginal band.
The foot is gray with a yellow margin and white submarginal band. The
rhinophores are pointed, tapering, and transparent white to yellowish
tan
with about 15 slightly darker lamellae. The gills are comprised of 7-8
transparent stalks with minute reddish flecks. (summarized from
notes that Scott Johnson took upon examination of the living
nudibranchs).
Natural history:
Chromodoris(?) sp.
#4
is a rare species known from only a few animals. It's nocturnally
active and has been found under ledges and in small
caves in
moderately exposed to highly exposed habitats from 8-15 m (26-49
ft). It lays a white
egg mass attached on its thin edge and there is no extra-capsular yolk.
Distribution:
Big Island and Oahu.
Taxonomic notes:
There
is
some question whether this species is a Chromodoris or Glossodoris. It
was first recorded in Hawaii from Puako, Big Island by
Scott Johnson on
April 27, 1981.
