The reticulated python of Southeast Asia is among the world’s two largest snake species (the green anaconda is equally bulky). The “retic” has killed humans before but is arguably more beautiful than it is dangerous. Photo courtesy of Flickr user Global Herper.

Where would we be without snakes? Rodent populations might boom, the native bird assemblage of Guam would probably remain mostly intact today and 100,000 people every year would not die of venomous bites. As we can see, snakes bring both good and bad to the world we share with them. But mostly, these reptiles have been cast in the role of evil.

It’s easy to see why, if we just take a glance at the scariest of the lot—the venomous snakes. Indeed, it might take a very persuasive herpetologist on field sabbatical in Ecuador to convince the locals that the pit viper of his thesis focus is anything but a device of the devil. Throughout the New World tropics, roughly 2,000 people die every year from the bite of the pit viper (Bothrops atrox), known also as the fer-de-lance. Its close cousin, B. asper, goes by the same common names and is comparably devastating and said to be so aggressive it will chase people, bent on sharing some of its powerful venom. And in Africa, the black mamba (Dendroaspis polylepis) seems so wicked it’s absurd: It is the fastest snake in the world and can slither more swiftly than the average city cyclist pedals to work; it is the second-longest venomous snake, growing to 14 feet; it may strike a single victim repeatedly like a psycho with a butcher knife; its venom is so potent it can kill a horse—and a person in just 30 minutes; and, in bite victims who go untreated, the mortality rate is—get this—100 percent. In other words, nobody—that’s nobody—on a trek in the wilderness of tropical Africa, hours from the nearest doctor and without antivenin, survives the bite of the black mamba. As locals say, this snake delivers the “kiss of death.”

Stories of such creatures can leave indelible impressions on the tender minds of men—so indelible that no matter how plain and obvious it is that the harmless gopher snake—or king snake, or rat snake—is a peaceful friend of society that wants little more than to eat a rat (a job that somebody’s got to do, and how grateful we should be that snakes have volunteered), many people still call snake control and removal experts when one appears on their property. Forgive them, Mother Nature, for they know not what they do. Now, whether you love them or hate them, here are a few iconic species to watch for when traveling, from those wickedly venomous to those worth learning more about before you cast your judgment.

Eating rodents is a job someone on this earth has to do, and we should be glad it’s not us. This Burmese python has mostly downed a rat. Photo courtesy of Flickr user Orbital Joe.

The snake initially strikes at its prey and holds on, pulling the prey into its coils or, in the case of very large prey, pulling itself onto the prey. The snake will then wrap one or two loops around the prey, forming a constriction coil. The snake will monitor the prey's heartbeat to ascertain when it is dead.
