This small doridid, Doris viridis, is one which was photographed but not collected from a buoy chain having numerous attached invertebrates and thallophytes in Agonoura Bay (Zamami Island), within 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 February of 1999 in 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 very rare in the Kerama Islands ... he has seen only the above featured animal (pers. comm.). Atsushi has the same photo in his 1999 publication (p. 135, listed as Dendrodoris sp.). There is also an image of Doris viridis in Gosliner, Behrens, and Valdés (2008, p. 157).
- I don't have access to Pease's original 1861 description, however the word viridis in Latin means green which is certainly suitable for Doris viridis.
