  • Average lifespan: 10-20 years
  • Oldest recorded: 32 years

The rattlesnake belongs to the pit viper family, which includes other dangerous species such as the cottonmouth and copperhead. The snake gets its name from a rattle at the end of its tail that it shakes when it feels threatened or as a warning to potential prey.

The rattlesnake has a unique set of features that make it well-adapted to its environment. It has a triangular head and hinged fangs that can fold back into its mouth when not in use.

The rattlesnake also has heat-sensing pits located between its eyes and nostrils that allow it to detect the body heat of potential prey. This helps it to hunt effectively in the dark or even underground.

Rattlesnakes can be found across the United States and parts of Mexico, usually in deserts, prairies, and rocky areas near a source of water. They are predominantly nocturnal animals, so they are rarely seen during the day.

Reticulated pythons are semi-arboreal and like to climb trees, though adults prefer to stay close to the ground where they hunt prey such as birds, reptiles, small mammals, and even primates. While they are not venomous, they can squeeze the life out of their prey using their strong coils.
