Poison dart frogs are some of the most beautiful and intriguing creatures on the planet. They come in a wide variety of colors and patterns and their toxic secretions have intrigued scientists and laypeople alike for centuries. But just how do these little frogs poison you?
The toxins produced by poison dart frogs are some of the most potent on earth. They are used by indigenous hunters to tip their blowgun darts and as little as 2 micrograms of the substance can kill a human. The frogs don’t produce the toxins themselves but rather acquire them from the insects they eat. Scientists believe that the frogs use the toxins as a way to protect themselves from predators and that the toxins help the frogs to stand out from other potential prey.
There are two main groups of poison dart frog toxins: alkaloids and bufadienolides. Alkaloids are a group of naturally-occurring compounds that contain nitrogen and bufadienolides are a group of compounds that contain oxygen carbon and hydrogen. Both groups of toxins are incredibly poisonous and both can cause serious health problems in humans.
The most common alkaloid found in poison dart frogs is called batrachotoxin. This toxin is so potent that just 0.2 micrograms is enough to kill a human. Batrachotoxin works by interfering with the ion channels in cells which ultimately leads to the paralysis and death of the victim.
Bufadienolides on the other hand work by affecting the heart. These toxins cause the heart to beat faster and harder which can ultimately lead to a heart attack. Just 0.3 micrograms of a bufadienolide is enough to kill a human.
So how do these toxins actually poison you? If you were to touch a poison dart frog the toxins would quickly absorb through your skin and enter your bloodstream. Once in your bloodstream the toxins would quickly spread throughout your body causing serious health problems. In some cases the toxins can cause paralysis and death within minutes.
