Although most colubrids are nonvenomous (or possess venom that has no notable effect on humans), some species, such as those in the genus Boiga, can produce bites with significant medical effects. Colubrids form the largest family of snakes. 134 species of colubrids occur in Mexico. [6] Arizona elegans Kennicott 1859; Bogertophis rosaliae ...
Like all kingsnakes, the Mexican black kingsnake is a constrictor and is non-venomous. Their diet includes other snakes —particularly rattlesnakes which are also common to the region— and as a result, has developed a resilience to various kinds of venom. [5] This species will also consume small rodents, lizards, birds, and eggs. [1] [5]
The Mexican kingsnake is a smooth-skinned, slender, sub-cylindrical snake which is more flattened ventrally than most members of the genus Lampropeltis. It has a wide head, large eyes and a long tail. [3] Adults grow to a length of about 140–200 cm (55–79 in).
The Mexican garter snake (Thamnophis eques) is a species of snake of the family Colubridae. It is found in Mexico and in the United States ( Arizona and New Mexico ). This harmless snake is semi-aquatic and most of the 10 recognized subspecies are restricted to lake basins in Mexico .
The Mexican milksnake has distinct red, black and cream or yellow-colored banding, wrapping around the body. This coloration is, likely, an evolutionary survival tactic to ward-off potential predators by mimicking the venomous coral snake which shares much of the same habitat; this has led to the species sometimes being called a coral snake-"mimic".

The Tropidophiidae, common name dwarf boas or thunder snakes, [2] are a family of nonvenomous snakes found from Mexico and the West Indies south to southeastern Brazil. [3] These are small to medium-sized fossorial snakes, some with beautiful and striking color patterns. Currently, two living genera, containing 34 species, are recognized. [4]
This snake was first described as species new to science in 1942. [2] Subsequently, some authors have noted similarities between northern populations of the Mexican wandering garter snake and the southern subspecies of the western terrestrial garter snake (Thamnophis elegans vagrans), leading them to reclassify the former as another subspecies of the western terrestrial garter snake under the ...
