Venomous Snakes of Texas
All four of the major species of venomous snakes native to the continental United States can be found in Texas: copperheads, rattlesnakes, cottonmouths and coral snakes. All together, there are 15 types of snakes that are venomous. Copperheads, with reddish brown bands on a lighter body, frequent rocky and wooded areas. Cottonmouths are dark brown, green or black and live in and around water. Texas is home to eight different species of rattlesnakes, identifiable by their distinctive tails. The coral snake, with its colorful bands of red and yellow on a black body, is found only in the southeastern part of the state.
Common Nonvenomous Species
Most snakes in Texas are not venomous. If threatened and approached, they may bite and even draw blood, but no venom is injected and the only damage will be the small flesh wound. Common species include rat snakes, hognose snakes, indigo snakes, racers, green snakes, water snakes and garter snakes. Texas has a variety of interesting and unusual species such as blind snakes and worm snakes.
Snake Safety
If you're going hiking in the Texas countryside, wear boots that offer protection to your ankles and calves and be careful in stepping over logs, rocks and other places snakes favor. Watch where you put your hands when climbing. Remember that a snake does not consider you its prey and will be happy to retreat if not cornered. Do not touch a dead snake, as the biting reflex can continue for hours after death. To keep your yard free of snakes, keep it clear of piles of brush, sheets of plywood, rock piles and similar items under which snakes like to take shelter.
Snake Facts
Snakes play an important role in the ecosystem by keeping populations of rodents and insects in check. They are mostly solitary and shy creatures and function best in moderate temperatures. Even in Texas, snakes hibernate during the coldest months. A snake's tongue is an important sensory organ, with which it captures microscopic scent particles that lead it to food and away from danger.
