This is one of a number of species with black lines and an orange border, loosely grouped into the Chromodoris quadricolor colour group. This species is distinguished by the orange or orange-brown lines between the black lines (usually 5 in number) and the orange border which is submarginal.

Hi Bill and readers!
I am pleased to announce that Chromodoris colemani has been found at Old Woman Is off Mooloolaba in sunny Queensland on the site called the Wall from our new dive boat MV Godiva.

Has this species been found in southern Queensland?

We have very few records of C. colemani, so few in fact that I sometimes wonder, even though I named it, whether it a colour variant of another, more common species. The only records I have of the species are from Bushy Island, near Mackay and Lizard Island, both in 'Far North Queensland'. Your find is therefore a valuabale addition to our knowledge both in geographical distribution and colour pattern. I have my doubts about most of the animals on the Forum I have previously identified as this species, but until we have more information it's difficult to be sure.

I believe that the LOWER RIGHT and LOWER LEFT images are Chromodoris colemani. It is common at Hachijo Island, Japan. And I often see C. colemani and C. striatella nestling closely together as in the UPPER photo.
Looks like these animals have mutually good relations.

Thanks for these interesting photos. I am pretty sure these animals are all Chromodoris colemani. When you often see similarly coloured animals associating closely together like this you can be fairly confident that they are the same species. Chromodoris striatella has many more black lines than these animals and the gills and rhinophores have a pattern of white spots.
What is interesting about your photos is that the lower two show a colour form similar to the animals I have been keeping on a separate page labelled Chromodoris cf. colemani because I wasn't sure of their identity. Your photos certainly lend support to the idea that they are a colour form of Chromodoris colemani.

I believe Chromodoris colemani from the Marshall Islands is another range extension. I have these from both Kwajalein and Utirik Atolls, where they seem to prefer midlagoon pinnacle reefs, living in pretty much the same habitat as C. elisabethina. In the photo of E177-2, I believe but am not certain that the animal is eating the purple sponge it is on. I could not really tell if there were grazing marks on the sponge, although the nudi was in a position that looked like it was feeding.

We don't know too much about this species, so any clues are welcome,

Have you had a chance to look at the other images I sent you with the last batch? No rush but thought I would remind you - especially the Chromodoris cf colmani from Dampier Archipelago (Pilbra region of W. Australia)- would like to finish this one for the report.
I'm pretty sure this is a colour variant of C. colemani. It has parts of the 5 black lines and the interspersed orange-brown lines. I am still not sure whether the animal I have on a separate page as Chromodoris cf. colemani is the same.
By the way the spelling in 'colemani' with an 'e'. It is named after Neville Coleman not Phil Colman.

Here is a photo from my latest trip to the Philippines. Please excuse the poor quality - the camera didn't work allright. I don't know the reason why - after the second week I misplaced the o-ring and the housing got full of water. The Chromodoris looks a bit like C. colemani ...

Sorry about your camera story - saltwater and cameras can be very depressing.
Your photo seems to be Chromodoris colemani as you thought.
