In 2015, on the last hike of the summer, we came across a jumping pit viper (Atropoides nummifer) and brazenly (or foolishly) photographed, labeled, and finally removed it from the Gamboa trail.
I ran into two Bothrops asper (Fer-de-lance or Terciopelo) on Las Cruces trails (one on Sendero Selva and one on the Water Trail) this year (so far), which is two more than any other year since 2013. Below are a few images of the two.

Anolis (Norops) aquaticus has bluish-green eyes, while the Anolis oxylophus has coppery eyes, as I’ve written about before. Here are those pretty eyes.
Often epiphytic, this individual is planted in the ground at the botanical garden. When the leaves die, the vascular tissue remains intact while the tissue between decomposes, leaving a net-like, tannish leaf outline on the forest floor.
