Abstract: Epitonium tinctum and E. indianorum are two mesogastropods which feed predomimantly on the tentacles of various anemones. Laboratory experiments show that they may locate anemones using a chemosensory method. Both produce a purple dye, which may be a carotenoid; and both produce a toxin or anesthetic which is either a large molecule or is attached to a large molecule. The toxin inhibits the compound action potential of the sciatic nerve of Rana pipiens and also the contractions of tentacle from Tealia crassicornis.
