Based on his more than 40 years of field research, Means, an expert on the eastern diamondback rattlesnake, reveals the biological complexity and beauty of the animals he has studied. In Australia, Means searches for the fiercey, reputed to be the world's deadliest terrestrial snake. In Mexico, he stalks the rattlesnake that might have served as the model for the mythical plumed serpent of Mayan art. In Florida, he is chased by cottonmouth moccasins. Through his experiences, Means hopes that readers will gain a new appreciation for animals called herps, or creepy-crawly things.
