Boidae

The Boidae ( boïdés ) form a family Serpent S constrictors in which one finds the boas but also the pythons. The constrictors kill their preys by constriction by enclosing them in their rings, contrary to many other snakes which use to them Venin (boïdés are deprived besides by it).

The boas meet mainly in the tropical zones like with Madagascar and in the south of the peaceful . The pythons meet in Africa, in Australia and in Asia, the boas of sands meet is of Africa to the India. They are snakes living in varied mediums, energy of the rainy forest to the deserts, while passing by moderate zones. These reptiles are Ovovivipare S, except the pythons which are them Ovipare S and thus lay eggs (certain species having even behavior of monitoring of the places of laying). They are carnivorous and consume various Mammifère S, Oiseau X and reptiles. One finds some of all the sizes, of less 1  measure for smallest Espèce S and until more 10  meters for largest like the Python reticulatus .

Subfamilies

One distinguishes three subfamilies from boïdés: the Boinae (Gray, 1825) - or boas , the Erycinae (Bonaparte, 1831) - or boas of sands and the Pythoninae - or pythons .

Note: according to classifications the subfamily of Pythoninae is regarded as a family with whole share called Pythonidae .

Boinae - boas

They are snakes of intermediate size which one can primarily find in South America, but also with Madagascar and the the Solomon Islands.

kinds of this subfamily:

  • Acrantophis Linnaeus, 1758 - terrestrial boas of Madagascar
  • Boa Linnaeus, 1758 - boa
  • Candoia Gray, 1842
  • Corallus Daudin, 1803
  • Epicrates Wagler, 1830
  • Eunectes Wagler, 1830 - anaconda
  • Sanzinia Linnaeus, 1758 - arboricolous boas of Madagascar

Certain authors (Kluge, 1991 & 1993) synonymisé the kinds Acrantophis and Sanzinia with the kind Boa . These the first two kinds thus do not appear in some classifications.
Certain authors also classify two kinds, Exiliboa and Ungaliophis , in this subfamily (Pough and Al , 1998 for example). They are in addition placed in a separated family, the Tropidophiidae.

Erycinae - boas of sands

They are snakes of more modest size, than one finds in the south of the the United States like in Africa, Asia and in the south of the Europe.

Kinds of this subfamily:

  • Calabaria Gray, 1849
  • Charina Gray, 1849
  • Eryx Daudin, 1803
  • Gongylophis Wagler, 1830

The kind Lichanura does not exist from now on any more, because it was synonymisé with the kind Charina (Kluge, 1993).
The statute of Charina is still discussed, and certain authors propose to amalgamate the kinds Eryx and Gongylophis .

Pythoninae - pythons

Kinds of this subfamily:

  • Antaresia Wells & Wellington, 1984
  • Apodora Kluge, 1993
  • Aspidites Peters, 1877
  • Bothrochilus Fitzinger, 1843
  • Leiopython Hubrecht, 1879
  • Liasis Gray, 1842
  • Morelia Gray, 1842
  • Python Daudin, 1803
