I had read that the giveaway is the bigger really round sticky pads, native fl tree frogs have a bit smaller and not quite as round. He jumps like a monster, 15-20 ft when he's mad at me.
There is a feature of the Cuban Tree Frog that is unique to its species. The skin on the top of their head between the eyes is actually connected to the skull and so doesn't move or freely slide against the bone. This is completely unique to the species.
