Talk about playing with your food.
Scientists have discovered a poisonous frog that takes up a toxin from its food and makes the chemical even deadlier. It's the first example of a frog using chemistry to make a poison for its own defense stronger.
This 4-centimeter-long green poison dart frog, Dendrobates auratus, can increase the power of a particular toxin that it picks up from its food.
