The fer-de-lance is one of the largest and most poisonous snakes in the world. In fact, it causes more human deaths than any other American reptile. This fierce killer has a special feature that helps it catch prey: a sensor located on its head allows it to detect heat given off by warm-blooded animals so the snake is able to strike its victims with near 100% accuracy—even in total darkness! Packed with fascinating facts and large, colorful photos, Fer-de-lance: Master Killer! introduces young readers to the natural habitat, physical characteristics, diet, and behavior of this master killer.
