Chelidonura feeding

September 8, 1998
From: Davide & Giovanni

We have plenty of red Convolutria retrogemma (red flatworm) in our tank. J. Sprung says that the nudibranchs of the genus Chelidonura feed exclusively on acoel flatworms and C. varians feed on red flatworms. Can you tell us where we can find some of C. varians?
Thank you.
Davide & Giovanni.

Dear Davide & Giovanni,
I am very interested in your report that species of Chelidonura actually feed on flatworms. I have been trying to discover what they feed on for about 30 years! I have long suspected flatworms but have never actually caught them in the act and once the food begins to digest there are no recognisable remains in the gut. Is J.Sprung a friend or are you referring to a book? I would be most grateful for a reference to evidence of Chelidonura actually feeding on something.

As to where you can find Chelidonura varians. It is not the most common species, but is often reported from shallow sandy lagoons and pools on coral reefs in both the Indian and Pacific Oceans ... Bill Rudman.
