Species Account:

        Chromodoris magnifica is considered to be rare on Okinawa as I have seen and collected a total of nine individuals (the initial specimen was collected in May of 1991 and the most recent during May of 1997) over a period of well over twenty years of diving here. C. magnifica is one of several very attractive striped chromodorids found here; it's however the only striped Chromodoris having a series of broad black longitudinal lines on the dorsum. I have a very similar unidentified black-striped Chromodoris which may turn out to be Chromodoris africana, but it's identification is unconfirmed as of this writing.

        The above featured animal was found and photographed crawling on the red demosponge in the photo. An additional animal was photographed upon a similar appearing red sponge, but it was not collected (also at Seragaki from 41m during August of 1993).

        Rudman (1982) points out the sparsity of records on this attractive animal and possibly the above animal will be a range extension on known records.
