An unidentified Glass frog (Centrolenidae) from an unknown locality. I suppose it could be a Reticulated Glass Frog, Hyalinobatrachium valerioi, but perhaps you, expert zoologists and herpetologists in Tumblr, could help with the ID of this frog.

"It has large yellow round spots and small black dots on a green background, so that it mimics the appearance of an egg clutch (Leenders 2001). The upper surface is shagreened (with small, rounded bumps). As with other glass frogs, the venter is transparent; the heart is visible and red, but the digestive tract, pericardium, and liver are wrapped in a white guanine coat. This frog has a broad head and a snout that appears truncated both in profile and from above. The eyes have gold irises and are not protuberant. The tympanum is not distinct. Digital discs are present and truncate. The first finger is longer than the second, with webbing present between the outer fingers. Toes are extensively webbed. Males have a white nuptial pad consisting of a few separate glands on the outer margin of the thumb base." (Savage 2002; Leenders 2001)
Yes it is.
