Crotalus durissus

Crotalus durissus, commonly known as the South American rattlesnake, is a venomous snake found in countries like Brazil and Colombia. It has a distinctive rattling sound when threatened and a slender body with a patterned skin. Its venom contains neurotoxins and enzymes that can cause paralysis, tissue damage, and other serious health issues if bitten. Despite its dangerous potential, it generally avoids humans and only bites in self-defense. Medical attention promptly following a bite is essential for effective treatment, which often includes antivenom and supportive care.
