Bothrops asper, commonly known as the fer-de-lance, is a venomous pit viper found in Central and South America. This snake is recognized for its distinctive triangular head and can vary in color, often displaying shades of brown, green, or gray. It typically inhabits tropical forests, grasslands, and agricultural areas, making it one of the most common snakes in its range. The fer-de-lance is known for its potent venom, which can cause severe tissue damage and is potentially fatal to humans. It primarily feeds on small mammals, birds, and amphibians. Due to its aggressive nature and proximity to human populations, it is considered a significant medical concern in areas where it is found.
