Map Treefrog (Hypsiboas geographicus)

Notice anything different about this Map Treefrog (Hypsiboas geographicus)?

How about its eyes? How about the different color of each eye? I can't explain the difference, and if anyone out there can shed some light on this, I would appreciate the information.

And yes, I moved the frog from the leaf to the other location. It was done very carefully, with minimal handling to avoid bruising. Amphibians have very delicate skin, and any bruises can encourage entry by parasites or fungi, leading to the death of the frog.
"Primum non nocere" remains the Golden Rule of responsible nature photography--"First, do no harm!"

Polkadot treefrog on water hyacynth in Peruvian Amazon

This little fellow was carefully placed on the water hyacinth several yards from the place where he was found. This environment is a natural one for him (or her), so the question is: Is this a captive specimen?
I think you could make valid arguments in either direction.
I was pleased with the aesthetics of the image, and was not overly concerned. The frog was free to travel and eventually hunkered around to the bottom of the leaf for the remainder of the day without any additional encouragement.
Technically, I was also pleased--fill flash was used to bring out some of the fine detail, but its effects are unobtrusive, as they should be.

Any comments?
