Merdigera obscura is a terrestrial snail in the family Enidae living from western Europe to Uzbekistan. It has a great scientific name.
Its generic name Merdigera is derived from a French word “merde”, that means faeces and from a Latin word “gerō”, that means bearer. Its specific name obscura is derived from a French word “obscur” and from a Latin word “obscūrus”, that means obscure and probably originally means “over” + “covered”.
Its shell is really covered with faeces and with mud. It serves as a camouflage.
