Okenia rhinorma Rudman, 2007
Maximum size: 4-5 mm.
Identification:
This
is a distinctive species with very large rhinophores that have
many cup-shaped lamellae
on their posterior faces. There are three processes on each side of the
body (the anterior pair short and forward pointing) and the body is
translucent-gray flecked with white, brown, and yellow.
Natural history:
Okenia rhinorma is
known from two animals. The first was found in a moderately exposed
location at a depth of
3-7
m (10-23 ft). It showed a nocturnal activity pattern while held. The
second was found on a rocky substrate at a moderately exposed site at 9 m
(30 ft).
Distribution:
Maui: widely distributed in the Indo-Pacific.
Taxonomic notes: It was first
recorded in Hawaii from Black Rock, Maui by
CP on April 4, 2006. There's some chance that it might turn out to be different from the Indo-Pacific O. rhinorma.
