Description

Everyone else on the observation team had passed right by this snake without seeing it. I had been standing only a few meters away watching the monkeys before I noticed it. I let Joe and Anaid know so they could see it too. It was quite large and looked dangerous, so I snapped a quick picture and we got out of there. When Elsa saw the picture, she said it was a nauyaca.

Description from Wikipedia

Bothrops asper is a venomous pit viper species ranging from southern Mexico to northern South America. Sometimes referred to as the "ultimate pit viper", these snakes are found in a wide range of lowland habitats, often near human habitations. Its proximity to human habitations is likely the reason why it is considered more dangerous to humans than others. This species is the main cause of snakebite incidents within its range. No subspecies are currently recognized.
