rhinophores & branchia
Okenia rhinorma Rudman, 2007
|Maximum size: 4-5 mm.
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.
Okenia rhinorma is
known from two animals. The first was found in a moderately exposed
location at a depth of
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
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.
3.3 mm: Black Rock, Maui; April 4, 2006.
