The jaw is opposite to the radula and reinforces part of the foregut. [2] The more purely carnivorous the diet, the more the jaw is reduced. [2] There are often pieces of food in the gut corresponding to the shape of the jaw. [2] The jaw structure can be ribbed or smooth:
A snail is a mollusc of the class gastopoda. Snails are extraordinarily diverse but all have coiled shells as adults to protect them and a strong foot coated in mucous for locomotion. All land snails are hermaphrodites and have two sets of tentacles which carry the eyes and olfactory organs. Articles this image appears in Snail Creator Al2
The columella (meaning "little column") or (in older texts) pillar is a central anatomical feature of a coiled snail shell, a gastropod shell. The columella is often only clearly visible as a structure when the shell is broken, sliced in half vertically, or viewed as an X-ray image.
The aperture is an opening in certain kinds of mollusc shells: it is the main opening of the shell, where the head-foot part of the body of the animal emerges for locomotion, feeding, etc. The term aperture is used for the main opening in gastropod shells, scaphopod shells, and also for Nautilus and ammonite shells.
This actually shows the jaw, against which the teeth on the radula act. Sphincterochila boissieri in Hamakhtesh Hagadol, northern Negev. Diameter is 2.1 cm. Underside of a snail climbing a blade of grass, showing the muscular foot and the pneumostome or respiratory pore on the animal's right side
In terrestrial pulmonate gastropods, eye spots are present at the tips of the tentacles in the Stylommatophora or at the base of the tentacles in the Basommatophora.These eye spots range from simple ocelli that cannot project an image (simply distinguishing light and dark), to more complex pit and even lens eyes.
