Bothrops atrox, commonly known as the fer-de-lance, is a venomous snake found primarily in the tropical rainforests of Central America and South America. It is recognized for its distinctive triangular head and patterned body, which can vary in color from brown to greenish. This species is known for its potent hemotoxic venom, which can cause severe tissue damage and is responsible for a significant number of snakebite incidents in its range. Fer-de-lance snakes are primarily nocturnal and are often found in a variety of habitats, including forests, grasslands, and agricultural areas. They are ambush predators, feeding on small mammals, birds, and amphibians. Due to their wide distribution and adaptability, Bothrops atrox plays a crucial role in the ecosystem as both predator and prey.
