English: Diagram showing an anterior-lateral view of the internal anatomy of a deep-sea gastropod, the true limpet species Bathyacmaea secunda (note that the diagram uses false color and a black background; the colors of the soft parts of the animal are in fact largely unknown, as upon bringing a specimen to the surface, it becomes "cooked" and colorless). Those organs with names shown in parentheses are located behind other organs in the diagram.
