Santa Cruz field station, Depto Loreto, Peru. January 20, 2013.
A very large toad with an equally large load of parotid gland secretions (see 2nd photo below). I’ve seen a few of these giants; despite their secretive nature, they do stand out in the beam of flashlight. They seem to become active just at dusk.
