Is a Texas rat snake poisonous?

The Texas rat snake (Pantherophis obsoleta lindheimeri) is a subspecies of rat snake, a non-venomous colubrid snake found in America.

As their name suggests these snakes are mainly found within the country of Texas, but their range extends into Louisiana, Kansas, Arkansas, and Oklahoma.

The Texas rat snake intergrades with different subspecies of rat snakes such as the black rat snake, hence the species exact range borders are impossible to ascertain.

These creatures are generalists when it comes to habitat, they are located in a wide variety of habitats from swamps or swampy areas, to forests or forests, stream valleys, grasslands, rocky canyons.

They’re even found in urban areas like Dallas, Fort Worth, or Houston, The existence of oak trees, and also many probably rodents are the single most important factor affecting their occurrence at any habitat.

The Texas rat snake has been a long, slender medium to big snake effective at reaching lengths of 4 to 5 ft (121 to 152 cm). Their character is rather competitive, and it’ll shield themselves biting and smearing their attacker with a foul smelling musk in their cloaca.

Occasionally they’ll vibrate their tails attempting to mimic a rattlesnake sound. On average those rat snakes will soon hit between 10 and 15 decades old more than 20 decades but some specimens may live.

The species varies considerably both in colour and patterning throughout extensive their range. Texas rat snakes have a yellowish or tan upper body, coated from head to tail with brown into olive-green, irregular blotching.

In some specimens is possible to locate some orange or orange red speckling. At the northern portions of their range, they are usually darker, although individuals be coloured and will have more yellow.
For example, a few specimens found in Sabine County are blackish with some white spots, which reflects the intergrade with all the black rat snake. Their stomach is usually gray in color or solid white.

To readily distinguish the Texas rat snake from the rat snakes we need to look for their head as they are the only species having a strong gray mind.

In addition, there are some remarkable colour variants within the wild such as large orange, albinos, hypomelanistic and leucistic. These morphs are consumed in captivity and eventually become rather well known.
