|Four shells of Myxas glutinosa, scale bar in cm & mm|
(O. F. Müller, 1774)
This snail is unusual in that it extends its almost transparent mantle to completely cover the shell when it is in motion, giving the very small animal a glass-like appearance. It also makes the animal sticky to the touch, hence its common name.
This species is European: it is now rare in western Europe, and even rarer in eastern Europe.
- British Isles - listed in List of endangered species in the British Isles
- This species is fully protected in the United Kingdom under the Wildlife and Countryside Act 1981 since 1981.

- List of non-marine molluscs of Ireland - extinct in Northern Ireland, still common in the Royal Canal and Grand Canal in central Ireland

- Germany - critically endangered (vom Aussterben bedroht)
According to the IUCN red list it is also native to Austria, Belarus, Belgium, Estonia, Finland, Germany, Kazakhstan, Latvia, Lithuania, Moldova, Norway, Russian Federation, Sweden and Ukraine.
This species requires pollution-free, extremely clear, calm water, in calcium-rich canals, streams and lakes.
It is rapidly declining or already extinct in many European countries, because of the loss of good habitat.
