First record of aquatic behaviour in an endemic terrestrial snail Indrella ampulla (Benson, 1850) (Gastropoda: Helicarionoidea: Ariophantidae)

Abstract

Indrella ampulla (Benson) is a highly endemic species found in the Western Ghats of India which has been regarded as a terrestrial or arboreal snail since its initial description. We report the first evidence of I. ampulla exhibiting the ability to survive and move underwater. This record could change our understanding of the species and will be beneficial to conservation and research on the species which are less likely to be restricted by water barriers than previously thought.
