Which of the following is not a venomous snake found in Texas?

The king snake is not a venomous snake found in Texas. This species is harmless and is actually known for its beneficial role in controlling the population of other snakes, including venomous varieties like rattlesnakes. King snakes are often characterized by their distinctive coloration and patterning, which can vary widely among different species. They are non-venomous constrictors, meaning they subdue their prey by coiling around it and suffocating it rather than delivering venom.

In contrast, the other snakes listed are indeed venomous. The copperhead, coral snake, and cottonmouth (water moccasin) all possess venom and are capable of delivering it through bites. Understanding the differences between venomous and non-venomous snakes is critical for safety and knowledge regarding wildlife in Texas.
