[1] This species is distributed in the Red Sea, the Indian Ocean along Aldabra, Chagos, South Africa, Kenya, Madagascar, the Mascarene Basin, Mauritius, Mozambique, the Seychelles and Tanzania; in the Pacific Ocean along Hawaii and New Zealand.

The outer surface shows a spiral sculpture without nodules, with a pattern of irregular dark stripes.

The mouth is rounded and the radula quite long, in order to adapt to the surface or the bark.

[5] These snails are grazers on the roots, trunks, branches, and leaves of their host plants where they feed on zooplankton, bacteria, algae and mangrove tissues.

These generalist herbivores daily vertically migrate along mangrove trees to avoid tidal submersion.
