Loreto Province, Peru. January 13, 2011.
This species has a reputation for delivering nasty bites, but the first two specimens found (one juvenile, one adult) were fairly calm and photogenic. I have such a good time finding these snakes while in Peru – we take the boat out at night to shine them in trees over the water, and adults sometimes show up along forest trails at night.
HerpMapper records for this species are here.
