Dendrobates Azureus (Blue Poison Dart Frog) series taken at a friend's house. This is a nice speciment of a blue poisonous frog. A friend of mine keeps them as pets (they are poisonous from their diet - so if you don't feed them stuff that makes them poisonous, they aren't)
So, if they become poisonous from their diet, how do you go about poisoning them if you need to get rid of a plague of them? ;-) Cool picture, by the way.
