Species Account:
Glossodoris cincta is considered to be uncommon on Okinawa; I've collected a total of six individuals over a period of many years here, but I've seen and photographed quite a few others. This attractive chromodorid is immediately recognizable by its undulating mantle edge and turquoise marginal band.
The featured animal was found crawling in the open on mixed silty-sand and coral rubble at 10:00am, during moderate low tide conditions while on SCUBA.
