This is a boa that I stepped on while walking in long grass in Corcovado National Park in 1988. I jumped about 7 feet. After I calmed down and realized that it was a boa, I caught the head in my insect net and carried it back to the station. Upon release, the snake climbed this guava tree and stayed there for 3 days trying to catch squirrel monkeys, which proved much too quick. Wild boas must be handled with care because they have a mouthful of nasty teeth and can bite viciously.

I found this frog on the beach at Corcovado after a major rainy season storm. It had apparently been washed out to sea and came ashore on the beach.
