The family Proteidae is a group of aquatic salamanders found today in the Balkan Peninsula and North America. The range of the genus ''Necturus'' runs from southern central Canada, through the midwestern United States, east to North Carolina and south to Georgia and Mississippi.〔(Mudpuppies, Mudpuppy Pictures, Mudpuppy Facts ). Animals.nationalgeographic.com. Retrieved on 2013-01-02.〕 The range of the olm, the only extant member of the genus ''Proteus'', is limited to the Western Balkans. == Taxonomy == Proteidae, is divided into two extant genera, ''Necturus'' with five North American species, and ''Proteus'' with one extant European species. They represent an ancient group, known from fossils since the Miocene. However, molecular data and a Laurasian distribution suggest origins that go further back.〔http://timetree.org/index.php?taxon_a=mudpuppy&taxon_b=olm&submit=Search〕 Family Proteidae * Genus ''Necturus'' * *Alabama Waterdog (''N. alabamensis'') * *Gulf Coast Waterdog (''N. beyeri'') * *Neuse River Waterdog (''N. lewisi'') * *Common Mudpuppy (''N. maculosus'') * *Dwarf Waterdog (''N. punctatus'') * Genus ''Proteus'' * *Olm (''P. anguinus'') * *†''P. bavaricus'' (Went extinct during the Pleistocene)〔 * Genus †''Orthophyia'' * *''O. longa'' (Miocene species)〔 * Genus †''Paranecturus'' * *''P. garbanii'' (Miocene species)〔 * Genus †''Mioproteus'' * *†''Mioproteus caucasicus'' (Middle Miocene)〔 * *†''M. wezei'' (Pliocene to Middle Pleistocene)〔 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「Proteidae」の詳細全文を読む スポンサード リンク
