The Southern Pacific rattlesnake is a venomous pit viper native to Southern California and parts of Baja California. Recognizable by its triangular head, keeled scales, and distinctive rattle at the end of its tail, this snake can vary in color from gray to brown with darker blotches along its back. It typically inhabits coastal sage scrub, chaparral, grasslands, and rocky hillsides. While generally shy and reclusive, it will defend itself with a venomous bite if threatened. Its venom can vary in composition, sometimes containing neurotoxic elements, which makes medical attention crucial in case of envenomation.
