Warts & All

American Toad (Bufo americanus)Double, double, toil and trouble;
Fire, burn; and cauldron, bubble.

Shakespeare’s witches open Macbeth by tossing a toad into their cauldron, along with parts of snakes, newts, bats and other dejected, unfortunate creatures. Why such a bad rap? After all, people LOVE frogs – they turn into princes, they have good tasting legs, and some cultures consider them lucky. But toads? Feared, reviled. What’s the big difference?

Toads tend to live in drier environments than frogs. In the frog’s aquatic environment, escape is just a hop away. For toads, though, warts are the key to survival. The two large “warts” on a toad, just behind the head, are glands that secrete a substance toxic to the toad’s predators.

Ay, there’s the rub – Toads are associated with poison. They actually produce three kinds of toxins: two affect the heart and one can produce hallucinations. Some cultures have used these chemicals for medical purposes. Perhaps those Shakespearean hags were just brewing up a treatment for edema.

Protect toads! While the American Toad is not threatened or endangered, many other populations of amphibians are experiencing sharp declines.
