| Abstract |
A specimen of about 11 mm shell height was found immobile within a rock crevice. It had two parasitic snails on its shell edge, and three small crabs were noted beside it (Fig. 1). This individual limpet appears to be somewhat deformed as the anterior portion of its shell seems to be smaller, underdeveloped, and having less pronounced ridges in comparison to its posterior part. The specimen was taken as a voucher. After cleaning, the shell was noted to have an ovate shape, rather elevated, and ribbed with thin, broadly granulated, scaled ridges. The orifice is ovate, rather broad and inclined to the shell’s anterior region. The shell is generally whitish with irregular, broad, dark brown markings that can also be seen on the shell’s interior surface (Figs. 2–7). |
