Angustopila dominikae is a species of light grey, round, land snails, a terrestrial pulmonate gastropod mollusc in the family Hypselostomatidae. Angustopila dominikae have been found in southern China, and are considered to be one of the world's smallest terrestrial molluscs (the holotype's shell height is 0.86 mm). [1]
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. Land snail is the common name for terrestrial gastropod mollusks that have shells (those without shells are known as slugs ).
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 iridescent nacre inside a nautilus shell Nacreous shell worked into a decorative object. Nacre (/ ˈ n eɪ k ər / NAY-kər, also / ˈ n æ k r ə / NAK-rə), [1] also known as mother-of-pearl, is an organic–inorganic composite material produced by some molluscs as an inner shell layer.
The shells of these snails often grow to a length of 18 centimetres (7.1 in) with a diameter of 9 centimetres (3.5 in). Certain examples have been surveyed in the wild at 30×15 cm, making them the largest extant land snail species known. [5] [6] Similar to other giant land snails such as L. fulica, A. achatina are herbivores. Their diets ...
The grove snail, brown-lipped snail or lemon snail (Cepaea nemoralis) is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc. [3] It is one of the most common large species of land snail in Europe, and has been introduced to North America. Subspecies. Cepaea nemoralis etrusca (Rossmässler, 1835) [4]
The anatomy of a common air-breathing land snail: much of this anatomy does not apply to gastropods in other clades or groups. Snails are distinguished by an anatomical process known as torsion, where the visceral mass of the animal rotates 180° to one side during development, such that the anus is situated more or less above the head. This ...
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.
