Green and Black Poison Dart Frog (Dendrobates auratus)

The Green and Black Poison Dart Frog is one of the species in this family that occurs in Costa Rica, along with the Strawberry Poison Dart Frog and other species. Poison Dart Frogs are diurnal, so it is relatively common to flush them from the floor litter during hiking trips through forested areas. Their contrasting body color is an adaptation to signal their venomous skin to potential predators, helping these frogs escape danger. They are small, although bigger than the Strawberry ones. Poison Dart Frogs are known because of their ability to withstand ant venom and convert it into their own which means the older the frog, the more venomous it probably is. Care has to be taken when handling venomous frogs, as contact with sensible parts of the human body can produce very unpleasant sensations.

A relatively big individual resting on green moss, most probably a female which are bigger than males.
This individual was moving quite a lot, which makes it very difficult to compose and focus. I do like the fact that a few moss leaves are sharp in this frame.
It is normal to see Poison Dart Frogs resting on the leaves of bromeliads, where they usually deposit their larvae, which will develop inside a water pool in the base of a bromeliad leaf.
Given the black patch covering most of the face, the black eye can turn almost invisible, even with the magnification of a macro lens.

I had to be careful not to touch this frog while taking pictures. If I got any venom on my hands and then not being careful I had touched my mouth or eyes, that would have been harmful

The camouflage pattern is pretty and unique among frogs

Venomous species like this one are more active during the day. I was also afraid of accidentally touching them, so kept some distance. They are very conspicuous when seen on leaf litter
