It was in the middle of the road just outside our laneway and our condominium complex guard was trying to convince the snake to move off the road and into the jungle area across from our house. He managed to eventually do this without harm to the snake. It was so amazing to actually see a fer-de-lance and this one was large. They are, however, not pet worthy. Here is what Wiki has to say: https://en.m.wikipedia.org/wiki/Bothrops_asper.
I made a video of our guard encouraging the snake to move off the road. He was able to do this without harm to himself but, really, these snakes are so dangerous.
Here is a screen snapshot of part of the video. You can see the snake with wide open jaws.
