Toxicon : official journal of the International Society on Toxinology 2022 FebHere we report, for the first time, a natural hybrid between Crotalus atrox and C. mictlantecuhtli based on intermediate characteristics of the external morphology and venom. Morphologically, the individual had characteristics of both parent species. The hybrid's venom exhibited an intermediate composition including the presence of crotoxin which has never been documented in C. atrox but is well documented in C. mictlantecuhtli. The hybrid's venom was highly toxic and showed an intermediate proteolytic activity between the parental species. The two Mexican antivenoms were able to neutralize the hybrid's venom's lethality.
