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]

[6] The typical habitat of this snake is rocky hillsides, valleys and deserts in mountainous regions [4] as well as woodlands, oak forests and grassy areas.

Its color may vary from gray to brown with a yellow underside. An adult O. aeneus perches in the tree on the left. Mexican vine snakes disappear in their natural habitat; their cryptic morphology provides them with highly effective camouflage. The body is laterally compressed. [4]
The dorsal color of these snakes may be brown, olive green, gray, red, orange, or pink. Ventral colors include the same as the dorsal, with the addition of yellow. Dorsal patterns may include stripes and there is typically a black stripe running down the center of the belly, which explains both the common and scientific names for this species ...
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 ...
