Adults rarely grow larger than 40 mm (1.5"), and are commonly about the size of a nickel. Shell coloration can be yellowish-gold, or light brown. Invasive - originated from Southeast Asia in the 1920s. Sexes normally separate but can be hermaphroditic and capable of self-fertilization - larvae remain in the parent's gills until reaching benthic adult form at ~1mm.
