There are three Long-snouted Tree Frog species in Costa Rica, with the Boulenger’s and Olive being both widespread and common accross wet lowlands in the country, and the Dry Forest species being common in the northwest region (Guanacaste). The Boulenger’s is mostly light brown, including the iris, with small patches of green and darker brown that provides better camouflage. It is arboreal and nocturnal, and males frequently call with their body upside-down during the wet season. To help hold this position, the innermost finger can be rotated up to 90 degrees, essentially pointing upwards, which provides a better grip on smooth surfaces like tree branches and trunks. The skin is granular, which might put off some people that call that appearance gross.

The body of this tree frog is covered in warts, so it can look repulsive to many people. Yet amphibians have a very important role in wet ecosystems, as some of the insect prey they consume might develop into plagues if unchecked.
Just as this frog grapples with the branch it was placed in, most amphibian species have been battling with declining populations. Protecting them from extinction is one of our biggest challenges.
The use of a shallow depth of field creates an interesting effect where the eye and face of the frog is extremely sharp, but the rest of the body is defocused.

I like shooting frog macros, because photos of small animals like this species that measures 5 centimeters of length can potentially be printed up to 1 meter length. That would look like a gigantic frog!
A lateral view where the long snout can really be appreciated. In Costa Rica, it is colloquially known as the “Rana Lagarto” (Crocodile Frog).
As with other frogs, the eyes are placed on the sides, enabling the frog to spot potential predators coming from both sides.
