Strawberry Poison Dart Frog, La Selva, Costa RicaThese guys are very small — only about an inch in length. They’re mostly spotted on the ground in leaf litter, but they also climb trees. In fact, mother’s will climb to the top of tall rainforest trees to deposit their tadpoles in the water of bromeliad plants growing from branches near the canopy. They are also called blue jeans frogs, as you can see from those legs. I photographed this one in central Costa Rica. Nikon D200 with Nikkor 70-200mm lens (at 190 with Canon 500D close up filter) ISO 100, f/5 at 1/6th of a second.
