Looks shopped. Goliath Frogs get a bit over a foot long, snout to vent. That would have to be a 16"-18" frog, and it doesn't even look right to be a Goliath.
I thought that might be the case as well, but I dunno.. I pulled it into Photoshop and couldnt see any obvious editing. Plus that frogs body is only as large as that mans shoulders to belly button, and I am betting he isnt over 5'8"
That's one that eats people legs! Ok then tell me why his left hand is behind the frog and the right hand can't be seen? I don't buy it because it would be too heavy to hold one-handed.
Yea he could be holding it in front of him, with a bent arm. But the picture looks like the guy that took it is at least 10' away. I dunno, I thought it was cool and thought I would share.
