How small is a Poison Dart Frog?…very small indeed. They call this one the “blue-jeans frog” in Costa Rica. This red and blue variety is the only variety I saw during my visit to the Costa Rican Caribbean lowland rainforest…but I know from trips to nearby Panama that there are other color variations possible. Poking around on google this morning it looks as though the blue-jeans and the strawberry (red-orange with black spots) are the most common in Costa Rica. The Oophaga species, including both the strawberry and blue-jeans, are poisonous, as the generic common name suggests, but only if eaten. You would have to hold one for a long time to run the risk of even a mild skin irritation…but, since they are small and fragile…it is not a good idea to hold them at all.
