Osteocephalus taurinus — Giant Broad-headed Treefrog
Also known as:
Manaus Slender-legged Treefrog, Bony-headed Treefrog
Uakari Floating Lodge, Mamirauá Sustainable Development Reserve, Amazonas, Brazil—November 14, 2006
This very large treefrog was hunkered down at night on the wooden walkway connecting the rooms at Uakari Floating Lodge when our guide Carlos called it to my attention. At first I thought it was the same type of frog as the ones preventing me from sleeping, but I later realized that it was larger, had a very different texture, and possessed the eyes that hypnotize.
Here is an account of the four days we spent at Uakari Floating Lodge in the Mamirauá Sustainable Development Reserve.
In Peru I've seen many of the closely related Osteocephalus planiceps, and at first I assumed this was another of that species. But the large size, somewhat different proportions, and lack of prominent white stripe on the upper lip indicate that this frog is O. taurinus instead.
