The snail Indrella ampulla from a tropical rainforest habitat in India. The shell in this species is reduced: the body cannot be fully retracted into the shell. The mantle is partly visible here as an area of off-white color under the edge of the shell. The rest of the body (head with retractile tentacles and most of the foot) is red. The foot fringe is off-white, with narrow black lines. The large caudal mucous pit is visible at the end of the foot.
