From Arenal, Costa Rica
On a night hike I found a litter frog.
Eyelash vipers are very deadly. They are also very fast. They can hang by their tail and wait for a victim.
This eyelash viper was in a branch over the trail at eye level. This was on a search for nocternal creatures near La Fortuna.
There was a trail that followed the river far out into the jungle along the river.
An old suspended bridge
In the river below the falls it was good swimming and there were a lot of good sized fish in the water.
Arenal Falls. It's a long steep hike down to the bottom of the falls but well worth it.
Swim at your own risk.
This is what the big volcano at Arenal looks like most of the time. There is almost always a mass of clouds over the peak.

Leaf cutter ants
This guy is holding one of the ants which is holding the leaf in its pinchers.
Green Parrot Snake, or Green Tree snake
This snake was the highlight of my trip.
Just don't get too close. They are really deadly.
