Reptiles of the Osa
In one of the most biologically dense places on earth, it's safe to say there are many different critters living around here. While reptiles aren't everyone's cup of tea, they are still very special and important facets of the greater ecosystems here on the peninsula. Between reptiles and amphibians the Osa Peninsula houses over 116 different species, and new species are still being discovered.
While it is unlikely that you run into a dangerous reptile here on the property, we do acknowledge that this rainforest is their home, and we always advise our guests to look where they are stepping and to always use a flashlight when walking around at night.
Common Basilisk
Basiliscus basiliscus
The Basilisk lizard is definitely a fan favorite for many animal enthusiasts. This lizard has been given the fun nickname "Jesus Christ Lizard" both in English and Spanish, due to its uncanny ability to appear to run across water.
This lizard is most commonly found hanging around rivers or streams. We recommend checking out the river underneath the bridge just south of the property where there have been many Basilisk lizard sightings.

Black Iguana
Ctenosaura similis
You will often find this scaly black iguana sunbathing on rocks or climbing through trees. These iguanas are found on the Pacific coast of Costa Rica. When they are babies they are hard to differentiate from the Green Iguana which is also local to the Osa Peninsula.
These iguanas can grow up to 1.3m (over 4ft) long and are truly an impressive sight to be seen.
Conservation status: Least concern (population stable)
