''Hedleyella falconeri'', the giant panda snail, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Caryodidae. It is the largest species of land snail to be found in Australia. ==Description== ''Hedleyella falconeri'' has a helicoid (spiral) shell and grows to a height of about . The colour is some shade of brown marked with radially arranged irregular bands and splotches of black. When the snail is quiescent, the head and foot are retracted into the shell, but these are extended when the animal wants to move around and feed. The upper surface of head and foot has a reticulate pattern in grey and the foot is rimmed with orange. The head bears two pairs of retractable, dark-coloured tentacles, the upper pair, with the eyes on their tips, being twice as long as the lower pair. There is a dark line leading from between the tentacles along the nape of the neck.
