The rattlesnake is designed with hollow fangs. When the rattlesnake bites its victim, the lethal venom travels through these hollow fangs and is injected into the prey's body. Rattlesnake species inhabit many different regions.

Rattlesnakes swallow their prey whole, then digest as the food passes though the body. On averge, Rattlesnakes in the wild eat only once every 2 to 3 weeks.

HABITAT: Timber rattlesnakes inhabit hardwood forest with rocky outcrops, pine flatwoods, bottomland hardwood forests, and cane thickets.

Rattlesnakes shed their skin several times a year, gaining one new rattle segment with each shed. There is no correlation between the number of rattles and the age of the snake (unless the snake only shed once a year).

Rattlesnakes have a special feeding system based on venom, injected into prey through teeth called fangs. Pygmy rattlesnakes use their tail more as a lure to attract prey than as a scare tactic.

Pygmy Rattlesnake
Sistrurus miliarius
The Pygmy Rattlesnake is called the "Ground Rattler" in parts of its range. The tiny rattle makes a buzzing sound audible only for a few feet.

These rattlesnakes avoid confrontation with humans; they are not prone to strike - preferring to leave the area when they are threatened. Like any animal though, these snakes will protect themselves from anything they see as a potential predator.

Young rattlesnakes don't have full-grown rattles. Instead, they have a small button on their tail. Timber rattlesnakes aren't very aggressive, so bites are uncommon. When a rattlesnake hears a person coming, it usually tries to get away and hide.

Pigmy Rattlesnakes may utilize "favorite spots" over and over. These may be preferred hunting or basking spots.
Prey and Hunting Techniques
Pigmy Rattlesnakes eat a wide variety of food items, including small rodents, lizards, and frogs.
