Myosotella myosotis

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.


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.[2]


As a native snail this species is found in the following countries and islands:

As an exotic, this species is found on:


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


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]
