In conclusion of this years Costa Rica stay, I want to show some of my favorite reptile & amphibian pictures I took during the last weeks. Starting with an impressive Annulated Tree Boa (Corallus annulatus). In Costa Rica, this boa only occurs in the Caribbean lowlands. The snake was about 150 cm (59 in) long.

The Central American Banded Gecko (Coleonyx mitratus) with its beautiful pattern and cute large head and eyes is my favorite Costa Rican gecko. They can be quite common in the right habitats in the northwest of the country, but not easy to find because of their nocturnal and secretive behaviour.

Another observation that I am very happy about, is this amazing Blue-sided Leaf Frog (Agalychnis annae). It was the first time for me to find this quite rare frog in the wild. After seeing hundreds of his red-eyed "cousins", it was really cool to find this golden-eyed beauty.

The Emerald Glass Frog (Espadarana prosoblepon) is more common and I have seen many of them during my night hikes, but for the first time, I was able to take a picture of its transparent belly. The process was very similar to the photography of the Reticulated Glass Frog one year ago.

Definitley one of my favorite Costa Rican snakes: False Tree Coral (Rhinobothryum bovallii). It is simply amazing to find this stunning and colorful snake climbing in the dark.
