Streptaxidae is a taxonomic family of carnivorous air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora. Six Streptaxidae subfamilies are accepted in the 2005 taxonomy of the Gastropoda by Bouchet & Rocroi. Streptaxidae are carnivorous except for one species ''Edentulina moreleti'', which is herbivorous.〔Gerlach J. (2001). "''Edentulina moreleti", the first herbivorous streptaxid (Gastropoda)". ''Phelsuma'' 9: 75. (PDF ).〕 All streptaxids have well-developed radula, except ''Careoradula perelegans'', which is the only known terrestrial gastropod without radula.〔Gerlach J. & van Bruggen A. C. (1998). "A first record of a terrestrial mollusc without a radula". ''Journal of Molluscan Studies'' 64(2): 249-250. .〕 Altogether 66 species from the family Streptaxidae are listed in the 2010 ''IUCN Red List''.〔IUCN 2010. IUCN Red List of Threatened Species. Version 2010.3. == Distribution == The historical area of origin of the Streptaxidae is probably Gondwanaland.〔Gerlach J. & Bruggen A. C. van (1999). "Streptaxidae Mollusca: Gastropoda: Pulmonata) of the Seychelles Islands, western Indian Ocean". ''Zoologische Verhandelingen'' 328: 1-60. (abstract ), (PDF ).〕 The Recent native distribution of Streptaxidae includes South America, Africa, Arabia, Madagascar, Seychelles, Mayotte, Comores, Mauritius, Réunion, Rodrigues, India, Sri Lanka, Andamans, South-East Asia and the Philippines.〔 The genus ''Gibbulinella'' is found in the Canary Islands.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Streptaxidae」の詳細全文を読む スポンサード リンク
