A small freshwater snail, Belgrandiella angelovi is a member of the Hydrobiidae family. Snails within this family rarely have any colouration in the shell, which is ordinarily white (4). However, in Belgrandiella angelovi, the shell is green-yellow, and has a silky surface. The shell is tiny, opaque and cylindrical, consisting of three to four-and-a-half slightly rounded whorls (3). The mantle is white (5) and the umbilicus is slit-like (2).
