Concerning message #19446:

Dear Bill,
Here are some pictures of Sebadoris nubilosa. One of them shows it's distinctive underside with submarginal dark-brown band. I hope it's interesting for the Forum to confirm its Indian Ocean distribution.

Locality: Saline Lagoon, 2 metres, Reunion Island, Indian Ocean, 28 December 2007, Night. Length: 200 mm. Photographer: Hugues Flodrops.

Best regards.

Thanks Hugues,

I suspect this species is often overlooked as it is so well camouflaged on sand and shell grit. As you say, the submarginal brown band on the underside of the mantle distinguishes it from other large dorids with brown spots on the underside. Other distinguishing external features are the soft pointed papillae on the mantle and the thin folded edge to the mantle - much like in some species of Dendrodoris

Best wishes,
Bill Rudman
