Known only from a couple of specimens, this species is one of the 'G. atromarginata group' of species with a high, very rigid muscular body, with a narrow radular ribbon. It is characterised by its brown body and whitish mantle border, and branched gills which give it its name. See also the similarly coloured Glossodoris cf. atromarginata.

My dive buddy Dave Mullins and I went searching for new species off Noosa at the north end of the Sunshine Coast, Queensland, Australia. We did 3 dives and found some very interesting subjects! This one appears to be Glossodoris dendrobranchia.
Water temp: 24C
Is my guess correct? Is this species only found at the Great Barrier Reef as you said in the Forum? Is this a one off find? Caves is a great dive site just north of Noosa.

You are certainly finding some interesting things at this site. This is almost certainly Glossodoris dendrobranchia from its colour. The other external distinguishing feature is the presence of some branched gills, which gives the species its name but they can't be seen in this photos as the gills are quite contracted. The only records we have of this species is from the Great Barrier Reef, but our knowledge of many of these species is fairly poor so we can't really say just how widespread this species is. Little bits of information, like your photo, all help
