Don’t Lick This Frog!

One of the most dangerous animals on the planet can be found in a rainforest in Colombia. Here’s how the poison dart frog kills—and why it might also save lives one day.

    What could be cuter than this little yellow frog? It’s less than 2 inches long! Look at its big, shiny eyes—and those tiny feet. They’re enough to make you smile and say awwwwww.

    But maybe you should be screaming—ahhhhhhhhh!

    Because that’s not just any frog. That’s a golden poison dart frog. It’s the most poisonous animal on the planet. 

    There are about 5,000 kinds of frogs in the world. Only about 220 types are poisonous. The golden poison dart frog is the most toxic of all. It has enough poison in its body to kill 10 humans.

The Amazing Rainforest

    Scared? Don’t be. You probably won’t see one of these frogs unless you travel to Colombia. That’s a country in South America. These candy-colored creatures live in a rainforest there. 

    Rainforests are some of the most amazing places on Earth. They cover just 6 percent of Earth’s surface. But they are home to more than half of the world’s plant and animal species.  These include beautiful blue lizards and pink dolphins that leap out of crystal-clear rivers.

    The tiny golden poison dart frog lives on the forest floor in the Chocó rainforest. If you spot one, don’t get too close. But you don’t have to run away screaming either. Poison frogs don’t bite or sting. Their poison is inside their bodies, just under their skin. When a frog is threatened, the poison oozes through its skin—kind of like sweat.  

    The frog’s poison is deadly only if it gets into a victim’s body. So unless you’re planning to lick a golden frog, you don’t have to worry.

The World's Rainforests 
A lot of things we use every day come from rainforests: wood, paper, chocolate, coffee—even lifesaving medicines. Sadly, rainforests are disappearing. One hundred acres are cleared every minute for farming and houses.

Powerful Chemicals

    But what if someone did lick one?

    Death would be quick. First, they’d go numb. Their heart would pound. Boom! Boom! Boom! They’d gasp. Their muscles would freeze . . . you get the idea. 

    The frog’s poison is a chemical known as BTX. It’s one of nature’s strongest toxins. But even though it’s so deadly, it could actually help humans one day.  

    That may sound surprising. But chemicals from other poisonous plants and animals have already been used to create lifesaving medicines. Scientists believe that BTX might treat people with heart problems or relieve pain.  

    Who knew that a little frog could be so powerful?
