Tarebia granifera is primarily a freshwater snail, although it has successfully inhabited estuaries with salinities close to marine levels in South Africa and Hawaii. The snail possesses a right-coiled, elongate-conical shell consisting of 8-12 whorls. Typically, the apex of the spire is eroded, and the shell’s sides exhibit a concave outline. Prominent nodes are sculptured along the suture between whorls, forming crenulations. Vertical and spiral ribs and threads further adorn the shell, with the base displaying noticeable spiral ridges. The operculum of Tarebia granifera features a small nucleus near the basal margin, rapidly expanding towards the top of the aperture. Adults of this species vary in size, ranging from 6 to 40 mm, but typically measure between 20-35 mm. The shell’s width is approximately 0.4 times its height.
