Very Cool! Following for more!
And the trivia:

Did you know that poison dart frogs obtain their poison from the insects they eat? Than cannot produce the poison on their own, so glands in the frog absorb the toxins/venom from their diet and secrete it as poison. If a frog never eats venomous insects, it never secretes poison. Also, if the frog was moved to an environment without venomous insects, the poison would naturally fade, and then the frog would be non-poisonous once again... Pretty cool!
