Corcovado: Best sighting by far

An eyelash viper (Bothriechis schlegelii). Absolutely gorgeous. Seen within the first 3 hours of being on trail entering Corcovado. Our guide caught site of a toucan off trail in the forest, pointed it out, started to continue on the trail to get a better view of the toucan...almost ran into this. Pretty venomous, but not quite as bad as the fer de lance -a very aggressive snake we saw later that night right next to camp :) I love reptiles. I mean, how can you not? Look how beautiful! All the green, red and bits of yellow. And, yes, this genus is known for modified scales above its eyes that remind humans of eyelashes, hence the anthropomorphic English common name (the spanish common name is Oropelo or gold skin to represent an all-yellow colour morph found in this species). If you look closely, you can see 3 or 4 scales above the eyes in this photo. Not to mention their long evolutionary history, enabling specializations like venom -one small bite and they kill something 50 or 100 times their size...I'm impressed.
