Atlanta peronii Lesueur, 1817

  • Spire contains 3½ to 3¾ whorls with deep sutures so that the whorls can be seen clearly. Juvenile specimens are difficult to identify from A. fragilis.

  • Sutures may be clear or pink and soft tissue colour varies greatly, from white to pink-orange to brown.

  • The adult shell is very large and can become a faint yellow colour.

  • The keel is of moderate height and becomes dark yellow in large specimens.

  • In very large individuals, the keel inserts between the final and penultimate whorls.

  • Eye type b, operculum type b, radula type II.
