Which of the following snakes is poisonous in Texas?

The Copperhead is indeed a venomous snake found in Texas, making it the correct choice. These snakes have a distinctive pattern and color that helps them blend into their environments, often in wooded areas and rocky hillsides. Their venom is hemotoxic, which means it affects the blood and tissues, but bites are not typically lethal to healthy adults, especially with prompt medical treatment.

In contrast, the Garter Snake, Green Snake, and King Snake are non-venomous. Garter Snakes are commonly found in gardens and grassy areas and are often harmless, though they can be mistaken for venomous species due to their markings. Green Snakes, which tend to be bright green, are also non-venomous and generally feed on insects. King Snakes are known for their ability to constrict their prey and are often mistaken for rattlesnakes, but they are completely harmless to humans. Understanding the characteristics of these snakes can help in both identification and ensuring safety while enjoying Texas's diverse wildlife.
