About this list

The species list comes from NAC 503.080 (Reptiles), combined with Commission Regulation 19-02 (non-native table) and the NDOW Species Information database (Nevada Legislature (regulations of the Board of Wildlife Commissioners), NAC Rev. 10/22/2025; pages retrieved 2026-11-03). 4 more entries come from other official sources named on each card.

Venom labels come only from official sources and link to them; "Not stated" never means harmless. How labels work.

"Nonnative" and "Invasive" follow the wording of the source list. See invasive species in Nevada.
