Species Account:

        Chromodoris tinctoria is an attractive dorid and is quite variable in its color pattern and it's frequently placed into a grouping known as the "Chromodoris reticulata complex". This complex is composed of a series of similar appearing animals having a reticulated pattern on the upper aspect of the notum. Rudman (1999) points out that the species differences suggested by different color patterns is not supported by a study of the internal anatomy. I've included several images of additional Okinawan animals, showing some of the variation found here.

        C. tinctoria is considered to be uncommon on Okinawa; I've only collected seven specimens but a dozen or so other individuals have been photographed but not collected. Another dozen or so have been seen but neither collected nor photographed. The above featured animal was collected from 49m during a daytime SCUBA dive and it was found crawling on the upper surface of a slab of coral rubble in an area of mixed sand and coral rubble.
