Crotalus oreganus
The Western Rattlesnake is a cool snake known for its rattling tail! It uses its rattle to warn others when it feels scared. These snakes can be found in many places and are important for nature.
Habitat: Desert
The Western Rattlesnake has a stout body with diamond or blotchy patterns, usually in shades of brown, tan, or grey, edged in white or cream. Its triangular head is notably broader than its neck, and it famously ends with a segmented rattle, making it distinct from non-venomous snakes.
