Costa Rica 2020 - Wildlife other than birds

Spectacled Caiman (Caiman crocodilus), Frio River in Caño Negro



Costa Rica has a rich biodiversity not only of birds. This page shows some photos of other wildlife I came across during my 14 days in Costa Rica. I saw the Spectacled Caiman and the American Crocodile, in addition to some species of turtles and lizards, but only one type of snake (the Eyelash Palm Pit Viper). Of mammals, I saw three species of monkeys, the two species of sloth (two-toed and three-toed), and the White-nosed Coati.

Frog photography is popular among tourists going to Costa Rica. In particular, the very beautiful Red-eyed Tree Frog is sought-after. I saw this species in Tortuguero and in the Sarapiqui area, and managed to get some nice images of it. Also displayed are some other frog species, and some lizard species. I am not sure about the exact ID of many of these species, but have attempted to name most of them (many are obviously wrongly named). This page also shows some photos of invertebrates such as damselflies, dragonflies and butterflies. The ID of many of the invertebrates are at best only suggestions.

A thank to Hans A. Olsvik for help suggesting family/name of the damselflies and dragonflies. Please keep in mind, some of these species are also probably wrongly named.
