Cypraea clandestina Linnaeus, 1767 (basionym)

Palmadusta clandestina is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.[1]

  • Palmadusta clandestina candida (Pease, 1865)
  • Palmadusta clandestina clandestina (Linnaeus, 1767)
  • Palmadusta clandestina passerina (Melv.)


P. clandestina has the flat-sided egg shape typical of cowries, and is around 26 mm long.[1] In a defence mechanism reminiscent of some other acid-producing cowries, this species secretes sulphuric acid when disturbed.[2]


This species is distributed in the Red Sea and in the Indian Ocean along Aldabra, Chagos, the Comores, Kenya, Madagascar, the Mascarene Basin, Mauritius, Réunion, the Seychelles, Somalia and Tanzania
