Meet The Costa Rica’s Poisonous Frogs!

Known as rain forest’s symbols, tireless performers of night choir concerts, owners of colorful and elegant dresses made of skin for tiny little bodies, frogs are synonym of Costa Rica’s natural wealth.

In our park we have the biggest ranarium in Costa Rica with plenty of frog species from the rain forest, which are really difficult to find in its natural habitat, so we recreated it to guarantee their life quality, conservation and so they can be admired by nature lovers that visit us.

There are more than 30 species of frogs and roads in Arenal Natura’s ranarium and here you’ll find the poisonous frogs from Costa Rica, which belong to two big families of poisonous amphibious, Dendrobatidae and Aromobatidae, commonly known as dart frogs or spearhead frogs.

The tiny frogs which belong to those families are called spearhead because the native tribes used the poison from the frog’s back to make spears and arrows to hunt. These amphibious live in tropical habitats such as Costa Rica, Nicaragua, Panama, or Colombia. there are more than 100 species, and the most poisonous is the Phyllobates terribilis: one gram of its poison kill 5000 people.

The poison is a toxin they have their skin, frogs produce it due to eating some insects which have the toxin. The body full of brilliant color works as an alert screaming “Hey! be careful, I’m poisonous”.

In our ranarium you also will find other non-poisonous tiny frogs like the cristal frog, the red eyed frog, or some even bigger like the bull frog.
