Yucatan has 188 species of reptiles, of which 74 are snakes and of this number, only 5 (6.75%) have some venomous quality. There are several myths associated to these animals that with a certain degree of knowledge can easily be denied. Snakes and in general all reptiles have a priority role in the food chains of different ecosystems where they inhabit, both as predators or prey. In other words, they keep the populations of insects, rodents and even other reptiles under control. As prey, they are an energy source for higher organisms in such chains. The purpose of this document is to make known the 5 species of venomous snakes of Yucatan. The following is a photograph of each of them, as well as scientific and common names: CORALILLO SNAKE (Micrurus diastema), RATTLESNAKE (Crotalus durissus), NAUYACA, and FAKE RATTLESKAKE- 4 NARICES. (Botrops asper), YUCATAN HOGNOSE VIPER. (Porthidium yucatanicum), HUOLPOCH, CANTIL SNAKE. (Agkristrodon biliniatus). The 5 species previously described, are listed with some protection status in NOM-059-SEMARNAT-2010, which refers to the environmental protection of native species of Mexico.
