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. [1]
Description
[edit]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
[edit]The complete nucleotide sequence of the mitochondrial genome of Myosotella myosotis has been available since 2008.[2]
Distribution
[edit]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).[3]
As an exotic, this species is found on:
- The West Coast of North America
- The East Coast of North America
Description
[edit]The maximum recorded shell length is 12 mm.[4]
Habitat
[edit]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.[4]
