Description edit
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.
Molecular phylogenetics edit
The complete nucleotide sequence of the mitochondrial genome of Myosotella myosotis has been available since 2008.[1]
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).[2]
As an exotic, this species is found on:
- The West Coast of North America
- The East Coast of North America
Description edit
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.[3]
