The term hognose snake is used to describe several snakes characterized by an upturned snout. The North American species (genus ''Heterodon'') are notorious for playing dead when threatened. The hognose snakes consist of three distantly related genera that are artificially grouped together by the "hognose" common name: ''Heterodon'', which are predominantly found in United States and northern Mexico, ''Leioheterodon'', the hognose snakes native to the Madagascar, and ''Lystrophis'', the South American hognose snakes. == Species == Genus ''Heterodon'': *Mexican hognose snake, ''Heterodon kennerlyi'' (Kennicott, 1860) *''Heterodon nasicus'' : *Dusty hognose snake, ''Heterodon nasicus gloydi'' (Edgren, 1952) : *Western or plains hognose snake, ''Heterodon nasicus nasicus'' (Baird & Girard, 1852) *Eastern hognose snake, ''Heterodon platirhinos'' (Latreille, 1801) *Southern hognose snake, ''Heterodon simus'' (Linnaeus, 1766) Genus ''Leioheterodon'': *Speckled hognose snake, ''Leioheterodon geayi'' (Mocquard, 1905) *Malagasy giant hognose snake, ''Leioheterodon madagascariensis'' (Duméril & Bibron, 1854) *Blonde hognose snake, ''Leioheterodon modestus'' (Günther, 1863) Genus ''Lystrophis'': *South American hognose snake, ''Lystrophis dorbignyi'' (Duméril, Bibron & Duméril, 1854) *Jan's hognose snake, ''Lystrophis histricus'' (Jan, 1863) *''Lystrophis matogrossensis'' (Scrocchi & Cruz, 1993) *Tri-color hognose snake, ''Lystrophis pulcher'' (Jan, 1863) *Ringed hognose snake, ''Lystrophis semicinctus'' (Duméril, Bibron & Duméril, 1854) 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「hognose」の詳細全文を読む スポンサード リンク
