Some aquatic snails are able to use chemical cues (kairomones) to differentiate between predators that have fed on snails and predators that have eaten other prey. However, it is unknown if terrestrial snails are able to differentiate between snail-fed predators and predators that have not recently consumed snails. Here we document diet-based chemical discrimination of a predator, the ground beetle Carabus carabus, by a terrestrial snail Theba pisana. When exposed to the feces of snail-fed… CONTINUE READING
