Chromodoris magnifica with 'satellite dish'

June 24, 2003
From: Ian Dunsmore

Hi,
I am very new at underwater photography but have been diving since I was a teenager in Scotland back in 1982 and much more frequently now in and around Indonesia for the last five years.

I live and work in Jakarta and was diving in Ahmed, north east Bali on some unexplored sites over a weekend on 30 and 31 May 2003. The attached photos were taken with a Nikoncoolpix5000 digital camera in about 24m on an isolated reef. This is a shore dive, water temp was the usual 28 or 29oC. Viz. was poor for north Bali about 15-20m.

I came across this chromodorid nudibranch which has this unusual cone shaped protrusion in between its rhinophores. It looks a bit like a loudspeaker. Perhaps a new warning device to potential predators. I attach three photos.

Best wishes,
Ian.

Dear Ian,
This is Chromodoris magnifca with an unusual deformity. What makes it doubly interesting is that we have recently had messages and photos of another chromodorid, Chromodoris kuniei, from Timor, with an almost identical structure which was likened to a satellite dish. I think your 'loudspeaker' or 'foghorn' idea is equally inventive. I have no idea what causes such a deformity. Hopefully it is not a sign of some pollutant in the water.
Best wishes,
Bill Rudman
