Marianina rosea is widely distributed in the tropical Indo-West Pacific region (Figure 1). Originally discovered in 1930 by the opisthobranch malacologist Alice Pruvot-Fol in the Isle of Pines, New Caledonia, this species has broadened its biogeography with specimens recorded in Australia, Taiwan, Hawaii, Fiji, Papua New Guinea, Japan, Phillipines, Malaysia, Kenya, South Africa, Madagascar, Guam, Singapore and the Marshall Islands (Marshall & Willan, 1999; Rudman 2000; Burn 2006; Debelius & Kuiter, 2007)
