Chelidonura amoena from Malaysia

July 19, 2002
From: Richard Houghton

Dear Bill,
Here is another from Pulau Aur, Malaysia
It was found in 10 metres of water on it's own, though close to other species. June 2002. I did find another about 25 metres away. Once brought together, the specimens started getting to know each other better, wrapping around each other in a small ball.

Thanks Rich,
This is Chelidonura amoena. It is a very streamlined 'bubble-shell' a specialisng in feeding on small flatworms which are sometimes quite common in reef environments. Like most sea slugs, these hermaphrodite animals tend to mate whenever they meet another of their own species. Considering their lack of site, their chances of meeting are quite slight, so it is probably an evolutionary necessity to be ready to mate, every time a meeting occurs.
Cheers,
Bill Rudman
