Opisthobranch of the Week Data
This attractive little cephalaspid, Noalda sp. 2, is unknown from Okinawa's main island as of late-May, 2011. The above featured animal is one which was photographed from a sandy bottom environment off of Zamami Island, one of a series of islands in the Kerama Islands Group, which are located 30 ~ 40 kilometers west of the Okinawa capitol, Naha. This featured animal was photographed by Atsushi Ono during April of 2009 in twenty-seven meters of water. Atsushi's photograph is used here with his kind permission. It should be noted that Atsushi considers the species to be rare in the Kerama Islands as he has collected only a single individual and has seen two uncollected animals (pers. comm.). I've added a second page w/ four additional images of the species from the Kerama Islands.
As of the current date (late Dec '11) three undescribed species of Noalda are known from Okinawan waters and are featured on these pages. These three species are:
Noalda sp. 1 Noalda sp. 2 - The above featured animal Noalda sp. 3
