There are creatures here whose direct ancestors hunted in these jungles before the first proto-mammals even learned how to regulate body temperature. These undeniably fascinating monsters are everywhere, and sometimes, when a person is very lucky, they reveal themselves. This one was waiting for me, hanging upside down from a rope rail on a small bridge close to where I am now. She traveled with me back to the lab clearing, where I left her again: hanging upside down from a twig, blending in to the foliage like an alien ninja, bobbing strangely among the green shadows. Millions of years of evolution daintily picked her way through the rustling leaves, quietly searching for prey.
