Myosotella myosotis, common name the mouse ear snail, is a European species of small salt marsh snail, a terrestrial pulmonate gastropod mollusk in the family Ellobiidae.
Description
For terms see gastropod shell.
The shell is yellowish to brownish, smooth or with fine striation. It is shiny. There are 7-8 slightly convex whorls. The apertural margin is white and usually with a white layer at the parietal side. The parietalis is very strong and horizontal and often a small second parietalis is present. The columellaris is strong and the umbilicus is usually covered. The form denticulata has 3-6 short and thin folds (like drops) near the palatal margin at the inner lip.
The complete nucleotide sequence of the mitochondrial genome of Myosotella myosotis has been available since 2008.[1]
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).[2]
As an exotic, this species is found on:
- The West Coast of North America
- The East Coast of North America
Description
The maximum recorded shell length is 12 mm.[3]
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.[3]
