Glossodoris charlottae Schroedl, 1999
It's always exciting to learn of a newly described species. One of the most recent chromodorids to join the described species list is Glossodoris charlottae. I first became aware of this species from the photo shown above from New Guinea, taken by Marc Chamberlain. Since that time it has been described by Michael Schroedl, as a Red Sea species.
Glossodoris charlottae is one of the chromodorid species that carries its mantle high off the substrate while crawling, exposing its white foot. It reaches up to 60 mm in length. The dorsal surface is deep brown, and depending on the specimen, has varying sizes and concentrations of orange and yellow spots (see Bill Rudman's Sea Slug Forum). The edge of the mantle has 4 bands of color - white, dark blue, pale blue and orange (from the outer edge inward, respectively). The gills are cream, and the rhinophores orange with blue tips. This species is pictured as Chromodoris sp. in Debelius (1997, p. 215) but dropped in his 1998 printing.
With its puzzling disjunct sightings in New Guinea and the Red Sea, it will
be interesting to see where else this species pops up as divers become aware
of it and report their findings to us. Let us know if you've seen this
