Viperidae
Viperidae (-arum, m.pl.) sunt familia Serpentium venenatarum, toto in orbe terrarum endemica, Antarctica, Australia, Hibernia, Nova Zelandia, Madagascaria, Havaiis, variis aliis insulis remotis et locis supra Circulum Arcticum exceptis. Viperidarum species praeditae sunt duobus dentibus veneniferis longioribus quam ceteri et reclinabilibus (unde alterum familiae nomen, Solenoglypha), ad venenum infundendum. Habitus typicus huius familiae, quem quisquis agnoscere potest, est corpus latius quam longum cum capite triangulo et cauda brevissima. Non modo Viperae similiaque genera circum mare Mediterraneum viventia, sed etiam crotalophori Americani sunt Viperidae.
