We found this frog during a night time hike in search of the Ghost Glass Frog at Yatama Ecolodge. It acted very docile, barely moving its head down from its upward position. The easiest way to recognize it among the Glass Frog family is by the dark spots on an otherwise uniform green skin. Males feature a blue-green hook, seemingly at the shoulder joint as in the left-hand side picture below; one can only ask what purpose this structure it might serve. The eyes are relatively forward facing, like in most other species in the family.
