Many of those seen by us were 2 to 5 foot long neonates and juveniles and were found in the shallows of the Rio Orosa. A few were 8 to 12+ footers and those were usually seen half submerged in remote creek channels during low water. The babies are active when disturbed and usually quickly attempt to escape. The larger examples, OTOH are usually quiescent, often defensive, and occasionally actually belligerent.

The large example depicted herewith, heavy with a prey item, was found as shown in this shallow creek. What isn’t shown is the fact that it was found during a cold early morning downpour. The night, not many hours behind us, had, during a Patagonia Express (cold front) dropped to 56F. That’s right. 56F in the Amazonian rainforest. Patti took the photo of the unhappy snake with a little point and shoot that she nearly sacrificed to the rain, the only pic taken of this memorable encounter.

Found on a cold day, this 12 foot long green anaconda was not happy to see us.
