A snail breaks up its food using the radula inside its mouth. The radula is a chitinous ribbon-like structure containing rows of microscopic teeth. With this the snail scrapes at food, which is then transferred to the digestive tract. In a very quiet setting, a large land snail can be heard 'crunching' its food: the radula is tearing away at ...
Lymnaea stagnalis, better known as the great pond snail, is a species of large air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae. The great pond snail is a model organism to study parasitology, neurology, embryonal development and genetic regulation.
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
A snail is a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name snail is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract
The adult bears a hard, thin calcareous shell 25–40 millimetres (1– 1 + 5 ⁄ 8 in) in diameter and 25–35 millimetres (1– 1 + 3 ⁄ 8 in) high, with four or five whorls. The shell is variable in coloring and shade of color, but generally it has a reticulated pattern of dark brown, brownish-golden, or chestnut with yellow stripes, flecks ...
As the snail grows, the new whorls of its shell will be smooth and glossy, consisting of only a brown color. A fully adult snail is around 7 cm (2.8 in) in diameter and 20 cm (7.9 in) or more in length, making it one of the largest of all extant land snails. [22]
