The fer-de-lance is a venomous snake found primarily in Central and South America. Known scientifically as Bothrops asper, it is recognized for its distinctive triangular head and striking patterns, which can vary in color. This snake typically inhabits forests, grasslands, and agricultural areas, making it one of the most common pit vipers in its range. Fer-de-lance snakes are known for their potent venom, which can cause severe tissue damage and is potentially fatal to humans. They are primarily nocturnal hunters, preying on small mammals, birds, and amphibians. Due to their camouflage, they can be difficult to spot in their natural habitat, increasing the risk of accidental encounters.
