Symbols of the tropical rainforest, tireless nocturnal carolers, bizarrely multicolored and sometimes poisonous, the rainforest frogs at our conservationist Frog Farm surely display an extraordinary variety. You can see it all, and learn all about them, while making your Costa Rican vacation naturally astounding!
Some rain forest frogs have evolved specialized body shapes to fit into the narrow spaces among bromeliad leaves, which store water at their bases and provide the ideal wet cradle for their eggs and tadpoles.
In the case of the Poison Dart Frog (named after the use Amazonian tribes gave their poison, smearing it on their arrows and blowpipe darts), evolution has created colorful warning patterns, as can be seen on the famous Strawberry Poison Dart Frog. This coloration is a very conspicuous warning that the frog is a bad tasting or even deadly meal for potential predators that share its habitat. Rainforest frogs feed mostly on insects and worms, catching them with their sticky, forked tongue, which is attached to the front of their lower jaw.
The Poison Dart Frog has attracted great scientific interest because of the discovery that it obtains the toxic chemicals it uses to defend itself from alkaloid-rich ants and other tropical rainforest insects. Furthermore, scientists have recently found that some Poison Dart Frogs not only absorb alkaloids from ants, but even have the ability to modify the substance, creating more toxic variants. The Poison Dart Frog's fascinating ability to resist, store, and manipulate toxins, along with its role in the rainforest food chain, are among the most important discoveries in the study of food chain evolution.
The Strawberry Poison Dart Frog or Blue Jeans Poison Dart Frog, (Dendrobates pumilio or Oophaga pumilio as it was recently renamed in 2006), is a type of Poison Dart Frog found in Central America, with a high concentration of individuals living in the Costa Rican tropical rainforest. It displays conspicuous colors as a warning to its predators that the frog has a bad taste and its ingestion may result deadly. The diurnal Strawberry Poison Dart Frog feeds mainly on ants, has very few predators thanks to its toxins, and can reach 5-6 years of age.
A tree frog has large adhesive toe pads, which enable it to climb smooth plant surfaces. One of its most common representatives, the Red Eyed Tree Frog (Agalychnis callidryas) is a nocturnal arboreal frog native to the American rainforest. It has a size of about 7-8 cms (2.8 inches). Its ventral skin is white, soft and fragile, but its dorsal skin is green, thicker and rougher. The sides of the frog are purple or blue, with distinctive vertical white stripes and orange toes. The bulging red eyes have vertically narrowed pupils, like a cat’s.
The Red Eyed Tree Frog feeds on moths, crickets, beetles and flies, among other small arthropods; but it can be eaten in turn by birds, turtles, lizards, snakes, bats and another mammals. Because it is not poisonous, it relies on camouflage for protection. During the day, the Red Eyed Tree Frog remains motionless, covering its blue sides with its back legs, tucking its bright feet under its belly and shutting its red eyes. It thus appears almost completely green, and well hidden among the foliage, but it recovers its astounding and bizarre coloring once in full activity. In its habitat, the Red Eyed Tree Frog lives from three to five years.
Don't forget that after an intense and active tour day you can relax in the hotel’s natural hot springs and enjoy the health and beauty of our Fangus Spa.
