Fourteen baits were tested in a “Y”-shaped maze for their attractiveness to the snail Australorbis glabratus. Wheat germ and an alginate-based snail food containing wheat germ were the only baits which attracted snails. One bait, ground watercress leaf, acted as a repellent. All other baits were found to be non-reactive. Human feces and urine did not appear to attract this snail.

Experiments also demonstrated that the osphradial organ is a chemoreceptor in A. glabratus and functions in the detection of attractive substances.
