Glossodoris atromarginata in the southern Philippines

Concerning message #21214:

Dear Bill,

I saw these Glossodoris atromarginata on corals. But the first one is longer, with almost 3 inches long and lighter color in the gills and rhinophores. While the 2nd and 3rd ones looks more round in shape. Both about 2 inches long.

Locality: Sunok, Southern Leyte, 15m, Philippines, 24 Dec 2007. Length: 2-3 inches. Photographer: Carrie Lo.

Cheers,
Carrie

Dear Carrie,

There are a number of species of Glossodoris with this general colour pattern so without an anatomical investigation I couldn't be 100% sure, but I think your photos are all G. atromarginata. This species is one of those with a thick body wall which makes the animal feel quite hard and rigid if you touch it. The difference in shape is just that the animal in your upper photo is stretched out crawling, while the others are 'curled up', resting or perhaps feeding, or investigating possible food sponges. I wouldn't be surprised if the animal in your bottom photo was feeding on the grey-brown sponge it is sitting on. If you look carefully there seems to be a whitish or lighter coloured patch in the centre which could be a feeding scar. I have illustrated a similar feeding scar in an earlier message [#19216]. If you have other photos of this animal whcih show the sponge more clearly I would be interested in seeing them. Possibly you have one in which the slug is slightly out of focus but the sponge is clearer - that would be perfect.

Best wishes,
Bill Rudman
