Nembrotha rutilans on the Great Barrier Reef

January 8, 2004
From: Paul Osmond

Note added 4 March 2008: Following Pola et al (2008) the name N. rutilans has been replaced by Nembrotha purpureolineata [see message #21419].

I believe this is Nembrotha chamberlaini found on the Great Barrier Reef off the coast of Townsville, Queensland in October 2003 although it does appear to be outside its stated range.

We found three separate indivduals on one reef at about 20m of depth.

Thanks,
Paul

Dear Paul,
One of the aims of the Forum is to find things outside 'their stated range'. The 'known range' of most species tends to reflect our lack of knowledge so don't hesitate to suggest we are wrong.

However I would identify this species as Nembrotha rutilans rather than as Nembrotha chamberlaini, but I think we have some way to go before we can be confident about stating how many species there are in this group. We either have one quite variable species or a group of similarly coloured species.
Best wishes
Bill Rudman
