Pyramidula chorismenostoma is a species of very small air-breathing land snail, a terrestrial pulmonate gastropod mollusk or micromollusk in the family Pyramidulidae.
The normal condition of the shell of this species is scalarid, i.e. the whorls of the shell are not attached to one another. This shell type is unique among the non-marine malacofauna of Europe. [2]
The width of the shell is up to 2.2 mm, the height is up to 3.1 mm. [2]
This species occurs in countries and islands including:
The Rodrigues starling is an extinct species of starling that was endemic to the Mascarene island of Rodrigues. Its closest relatives were the Mauritius starling and the hoopoe starling from nearby islands; all three are extinct and appear to be of Southeast Asian origin. The bird was only reported by French sailor Julien Tafforet, who was marooned on the island from 1725 to 1726. Tafforet observed it on the offshore islet of Île Gombrani. Subfossil remains found on the mainland were described in 1879, and were suggested to belong to the bird mentioned by Tafforet. There was much confusion about the bird and its taxonomic relations throughout the 20th century.
Theodoxus fluviatilis, common name the river nerite, is a species of small freshwater and brackish water snail with a gill and an operculum, an aquatic gastropod mollusk in the family Neritidae, the nerites.
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. However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water.
