Texas is one of the states with large snake biodiversity. Some of the rarest snakes in the country are found here.
Texas is the home to 10 species of Rattlesnakes, and 3 subspecies of Copperheads. The warm Texas climate is home to rare US species such as the Mojave rattlesnake and the Desert massasauga.
Venomous and non-venomous snake species are the most common in Texas as follows.
1. Western Ratsnake
Scientific name: Pantherophis obsoletus
Common name: Western rat snake, black rat snake, pilot black snake, simply black snake
The Western Ratsnake is the most common snake species in Texas. It represents an agile non-venomous species.
Western Ratsnakes are known for their innate ability to climb trees. They can climb a tree on the tree trunk without the aid of branches. These snakes are also good swimmers.
The versatile nature of the snake is also seen in its habitats which range from rocky mountains to woodlands.
Western Ratsnakes have a varied diet, mainly comprised of vertebrates such as rats and young rabbits. They also eat frogs and various lizards.
Western Ratsnakes use constriction as a preying technique. They squeeze prey until their cardiovascular system is suppressed, killing the prey before eating it.
2. Western Diamond-backed Rattlesnake
Scientific name: Crotalus atrox
Common name: Western diamond-back rattlesnake or Texas diamond-back
One of the common snakes in Texas, the Western Diamon-backed Rattlesnake is responsible for most bites around the country.
This species is aggressive and venomous. Its venom attacks the circulatory system and it often prompts muscle catabolism, a process where certain proteins in the muscles are destroyed.
The snake has been shown to grow up to 5 feet in the wild and up to 7 feet in captivity.
Western Diamond-backed Rattlesnakes are known for feeding almost exclusively on mammals. This is a potent snake that hunts and night and maybe in the morning.
While common in the state, the Western Diamond-backed Rattlesnake might not be as easy to spot during the day. This gray and brown snake prefers to hide below shrubs and bushes during periods of inactivity.
3. Western Ribbon Snake
Scientific name: Thamnophis proximus
Common name: Western Ribbon Snake
Part of the garter snake genus, the Western Ribbon Snake is identified by its small green body with yellow-white stripes.
The species is known for its reduced size as adults can measure up to 50 inches.
While shorter than other species, the Western Ribbon Snake is one of the species in Texas with specific preying techniques.
For example, it likes to thrust its head into a fake strike in multiple directions when planning to provoke frogs to exit their hiding spots. This makes frogs believe the snake’s attack.
Given its reduced size, the Western Ribbon Snake is also preyed upon by other species. Raptors and weasels are among their most common predators.
4. Plain-bellied Watersnake
Scientific name: Nerodia erythrogaster
Common name: Plain-bellied watersnake, plainbelly water snake

6. Diamondback Watersnake
Scientific name: Nerodia rhombifer
Common name: Diamondback Watersnake
The Diamondback Watersnake is known for its rough body due to its keeled scales. The species is adapted to living next to water sources.
Diamondback Waternskaes feed on multiple types of fish. Adaptations allow these snakes to dive their heads underwater looking for fish. Sharp teeth help them grab onto slippery fish efficiently.
These snakes can be seen during the day on vegetation overhanging various water surfaces. It tends to drop into the water to escape when seeing people.
The Diamondback Watersnake is highly aggressive towards people. It bites either when cornered or when roughly handled.

The Northern Cottonmouth is one of the snakes that has adapted well to living in the Gulf Coast barrier islands and the Southern US. It has adapted better than Cottonmouth snakes.
This is the reason why Northern Cottonmouth snakes can live both in fresh water and saltwater habitats.
Northern Cottonmouth snakes are both diurnal and nocturnal. They might not be seen easily during the day in some habitats as they prefer to rest in shaded spots.
These snakes feed on aquatic prey such as fish and frogs.
They also consume small turtles. Given the chance, these snakes also turn to cannibalism eating their young.
Scientific name: Masticophis flagellum
