The Mexican black kingsnake’s home is the Texas Hill Country, with the majority of the population found in the region around San Antonio and the surrounding area.

While the snake’s native habitat in the Hill Country is mostly grasslands and open prairie, recent poaching of their burrows and habitat loss throughout the region have driven them to seek out other locales to call home. It is not uncommon to see them around the city of San Antonio, including at our Serpentarium, which is located inside the San Antonio Zoo.

Geographic range and habitat

Mexican black kingsnakes are found from South Texas north to Chihuahua, where they spend their winters in caves or abandoned mines, and they migrate south to be active and nesting during the hot, dry summers.

Habitat: Mexican black kingsnakes inhabit many different habitats throughout their range, and they can also be found living under rocks and logs in a wide variety of habitats. They are one of the more common snakes in the arid, grasslands of the southern United States. However, these snakes need soil for burrowing and most prefer limestone to bedrock.

What do you need to know about Mexican black kingsnakes?

It’s a slimy snake. Unlike many snakes, you don’t need to be concerned about the redness of their skin. “The Mexican black kingsnake is very common in the southeast part of the United States and around the Gulf of Mexico, so there isn’t much need to be concerned about what it looks like,” says Pete Gurney, founder of the Gurney’s Reptiles in Milford, New Hampshire.

It is highly venomous. The Mexican black kingsnake is considered a “Highly venomous” snake, just like the rattlesnake. They are considered to be among the most dangerous in the Western hemisphere. Only three species of snakes – the copperhead, the cottonmouth, and the western diamondback – can be even considered equal in terms of pain inflicted from the bite.

The history of the Mexican black kingsnake

Historically, the Mexican black kingsnake was described by O.C. Marsh in 1887, but the species had already been spotted by zoologists over a decade earlier. The Mexican black kingsnake was spotted in southwest Texas and northern Mexico in the early to mid-1800s by sailors and travelers on ships and ships they encountered along the Gulf Coast.

Mexican black kingsnakes don’t live in ponds and marshes like their cousins the common and eastern kingsnakes do. They are often found in wet areas like parking lots and woodlands, where they are protected from predators by being embedded into the ground or lying in leaf litter. Unlike most black snakes, Mexican black kingsnakes have an olive-brown or tan coloration that extends well up to their bodies.

The Mexican black kingsnake in captivity

Both the Mexican black kingsnake and the black rattlesnake belong to the same subfamily, but they’re otherwise quite different. It has an elongated tail, it likes to burrow and it tends to live in urban areas, so the two species have been classified as two separate species.

An adult Mexican black kingsnake (Coluber constrictor sumneri) can grow to a maximum of 2-5 feet (60-90 cm), but most tend to be smaller than that. They tend to weigh around 40-70 grams, but, depending on the species, can weigh anywhere from 1-4 pounds (0.5-1.3 kg). The Mexican black kingsnake is completely harmless.

It is an ophidiophagous snake, meaning that it feeds on snakes. The Mexican black kingsnake doesn’t often live as long as other snakes, usually living around five to seven years.

The future of the Mexican black kingsnake

You can’t put a price on the conservation of an imperiled species, but we can tell you that the Mexican black kingsnake is worth more than just a little bit of money. The Mexican black kingsnake is a vital part of many native ecosystems, including grasslands, savannas, woodlands, and ponds.

Because of this, its habitat is under threat because of the introduction of invasive species like cottonmouth and copperhead, which prey on snakes.

Scientists like our expert snake specialist Ben Lawrence at the Southern Alabama Forestry Commission, also suggest that the best place to protect the Mexican black kingsnake is in native ecosystems. What happens if Mexican black kingsnakes go extinct?
