There has been some confusion over the taxonomy of the Nerita genus in the Pacific region, however Nerita atramentosa and Nerita melanotragus are now recognised as separate species (the two have often been considered to be the same species).
This nerite is endemic to the southern coastlands of Australia, including Tasmania, New South Wales, South Australia, southern Western Australia and Victoria. The similar species, Nerita melanotragus occurs to the east of Wilsons Promontory, while N. atramentosa occurs to the west.
This species is commonly found on intertidal rocks, particularly in the mid to upper intertidal zone. It prefers to attach to sloped or vertical rock surfaces, or hang from the underside of rocks. This may be a method of thermoregulation, as if N. atramentosa is on a horizontal surface, it will absorb the maximum solar radiation. By contrast, if it is on a greater angle to the sun, it absorbs less energy (and thus heat). N. atramentosa exhibits trail following behaviour. The species feeds by scraping epilithic algae using their radula. Nerites are preyed upon by reef crabs of the species (Ozius truncatus).
