Mimachlamys varia from the Adriatic - systematic overview
Here is a systematic collage of Mimachlamys varia (Linnaeus, 1758), taken from the Grado lagoon. Within this species, juvenile colours (i. e. umbonal region) often differ from the adult coloration of the shells. The collage shows special umbonal colours (assembled in columns) and their most common formae (f. violacea & rubra-fusca) in this location (rows). Also, the last row shows typical and more homogenous colour variations of M. varia.
