Myosotella myosotis, common name the mouse ear snail, is a European species of small salt marsh snail, a terrestrial pulmonate gastropod mollusc in the family Ellobiidae.
Description
For terms see gastropod shell.
The shell varies from yellowish to brownish in color and can be either smooth or finely striated, with a shiny surface. It typically features 7 to 8 slightly convex whorls. The apertural margin is white, often accompanied by a white layer on the parietal side. The parietalis is robust, horizontal, and often accompanied by a smaller secondary parietalis. The columellaris is also strong, and the umbilicus is usually covered. The form denticulata is characterized by 3 to 6 short, thin folds resembling droplets near the palatal margin of the inner lip.
Molecular phylogenetics
The complete nucleotide sequence of the mitochondrial genome of Myosotella myosotis has been available since 2008.
Distribution
As a native snail this species is found in the following countries and islands:
- Belgium
- Netherlands
- Great Britain
- Ireland
- Mediterranean Sea coasts (Spain, Italy, Istria, Dalmatia, Albania, Greece, West and South Turkey), West European coasts to Ireland and Scotland, Black Sea, North Germany (and Baltic Sea).
As an exotic, this species is found on:
Description
The maximum recorded shell length is 12 mm.
Habitat
This species lives right at sea level (at the highest high-tide level), and so therefore the minimum recorded depth for this species is 0 m, and the maximum recorded depth is 0 m.
