s, terrestrial
pulmonate gastropod mollusks in the family Zonitidae
.
of species in this genus is more or less transparent, subdepressed and contains an umbilicus. The aperture
is semilunar and usually lacks teeth. The outer lip is thin and sharp.
The animal is elongate and is able to retract completely within its shell. It has a more or less developed caudal mucous pit
. The mantle lobes are small and not reflected on to the shell. The genital orifice is somewhat distant from the right tentacle
. The jaw is marked by a median rostrum. The lateral teeth of the radula
are bicuspidate, while the marginal teeth are sharp and narrowly unicuspidate.

Description
The shellGastropod shell
The gastropod shell is a shell which is part of the body of a gastropod or snail, one kind of mollusc. The gastropod shell is an external skeleton or exoskeleton, which serves not only for muscle attachment, but also for protection from predators and from mechanical damage...

Tentacle
A tentacle or bothrium is one of usually two or more elongated flexible organs present in animals, especially invertebrates. The term may also refer to the hairs of the leaves of some insectivorous plants. Usually, tentacles are used for feeding, feeling and grasping. Anatomically, they work like...

Radula
The radula is an anatomical structure that is used by molluscs for feeding, sometimes compared rather inaccurately to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus...
