The banded chink snail is small, not exceeding 10 x 5 mm. The shell has five whorls. The color is usually light brown with two to four red-brown bands on the last whorl, although it is not unusual that the bands are absent.
The life span of the banded chink shell is no more than a year. It breads from January to early spring. The ring shaped jelly masses of eggs hatch to planktonic larvae.
It is usually seen on algae in the intertidal zone, but has been reported as deep as 40 meters. It tolerates a salinity as low as 20‰.
It is widespread in the northern parts of the Atlantic as well as the Pacific Ocean. It can be found anywhere along the coast of Norway.
