Frog x Snake x Me

A strange noise coming from the woods next to my office at the Arboretum; the dog that hangs out there was whimpering and showed reluctance to get any closer to the source of the disturbance. "Sounds like a cat in distress", I thought to myself. After hearing the sounds for a few minutes, I decided to have a closer look. To my surprise, I discovered a "papo-ovo" snake latched on to a rather large frog. The attack may have been going on for some time because the frog's right hind leg was swollen up and the anus of the frog bloody. Click on the images for enlargements. I decided to come to the frog's rescue by nudging it gently with my boot. It immediately released the frog and went for me. Third image. The frog remained put for a few seconds and then quickly jumped away to disappear into the woods nearby. I was impressed how fast the snake ran after it. It had no intention of losing lunch. I would like to think that the frog escaped, but I think it was much to crippled to to do so. The situation wasn't really any of my business, but I felt sorry for the frog.
