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[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 horizonal 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]

  • The West Coast of North America
  • The East Coast of North America

Description[edit]

The maximum recorded shell length is 12 mm.[3]

Habitat[edit]

This species lives right at sea level, and so therefore the minimum recorded depth for this species is 0 m, and the maximum recorded depth is 0 m.[3]
