South American rattlesnake
The South American rattlesnake, or Crotalus durissus, is a venomous snake native to South America. It features a distinctive rattle at the tail tip, used for warning predators. Its coloration varies from brown to gray with darker patches, helping it blend into its environment. The snake is typically found in forests, grasslands, and rocky areas. Its venom contains neurotoxins and myotoxins, which can cause paralysis and muscle damage in prey or bite victims. Despite its dangerous potential, it generally avoids humans, and bites are rare when proper caution is used.
