A novel anti-predatory mechanism in Indrella ampulla (Gastropoda: Ariophantidae)

Gastropods depend on their shells and slime for defence but they also have certain other strategies which serve as effective measures to avoid predation. This is an opportunistic observational account of individuals of Indrella ampulla (Ariophantidae) smearing their slime on the surface of their shells when agitated. Such a behaviour is novel to our knowledge and has not been reported earlier. This note will further add to the natural history observations of such animals and decipher the lesser-known facts about the defence strategies.
