Amazin' Amazon Mystery Animals

Candy on the forest floor? It might look like an already-licked sweet treat to eat, but the poison dart frog (or poison arrow frog) doesn't get its name from tasting yummy. In fact, if an animal did try to pop a dart frog in its mouth, the frog would pop right back out. That's because the poison in the frog's skin tastes terribly bitter, so bitter that the animal that tried to eat the frog will forever remember: sweet things don't always come in colorful packages.
