Chromodoris sp. #1

Maximum size: 50 mm (Kay &
Young, 1969).
Identification:
This
is
a
broad, flattened species with a white notum densely
reticulated in red, a yellow marginal band, yellow rhinophores and
orange-lined gills. The notum is decorated by a series of enlarged,
dome-shaped pustules with violet-red tips. The latter feature
distinguishes it from the similar appearing Chromodoris
petechialis and Chromodoris sp. #5.
Natural history:
Chromodoris sp. #1
is commonly seen in moderately protected to exposed rocky
habitats at depths of 6-60 m (20-197 ft). It is nocturnally
active
but may also be
found under rocks, crawling on sand, or resting in the open on shaded
cliffs during the
day. Scott Johnson reports
it apparently feeding on a white sponge. It lays a light peach egg mass.
Distribution:
Big Island, Maui, Molokai, Oahu, Kauai and Niihau: widely distributed
in the
Indo-Pacific.
Taxonomic notes:
Although
labeled
in
various sources on-line as a form of Chromodoris
tinctoria, this appears
to be a
distinct species based on the enlarged hemispherical pustules on the
notum, its solid-yellow rhinophores and its nocturnal habits. It is
listed as C. petachialis
in Bertsch and Johnson, 1981 and Kay, 1979. It is referred to as the
"red-spotted nudibranch" in Hoover, 1998 & 2006 and was probably
first
reported in Hawaii from Ala Moana, Oahu in Dec., 1961 (Kay & Young,
1969--as C. petechialis).
