Amphibians on Display
Frogs of Costa Rica
This display contains frogs from Costa Rica, including Green and Black Poison Frogs (Dendrobates auratus), Glass Frogs (Cochranella sp.), and Lemur Frogs (Agalychnis lemur).
Green and Black Poison Frogs are active in the daytime with bright colors. Glass Frogs have mastered camouflage as they are, to some degree, transparent. They are nocturnal, but usually sleep in plain view. Lemur Frogs are nocturnal tree frogs who lay their eggs on the under-side of leaves.
Blue Frogs of South America
The Dyeing Poison Frog (Dendrobates tinctorius) gets its name due to its use as a dye amongst tribes in South America. There are different color morphs of Dendrobates tinctorius, including Blue Poison Dart Frogs (Dendrobates azureus), which are easily recognized by their blue color.
Poison dart frogs can release toxins from the skin that are distasteful and potentially lethal to would-be predators. Toxic species of poison dart frogs from South America are utilized by Indians to poison the tips of blowgun darts.
Colombia's Dangerous Duo
The Dangerous Duo exhibit features two of the three deadliest poison dart frogs from Colombia, including the Golden Poison Frog (Phyllobates terribilis) and the Black-legged Dart Frog (Phyllobates bicolor).
These frogs flaunt their beautiful colors to intimidate potential predators. The frogs are lethally toxic in the wild, but when raised away from their natural food source they are harmless. The endangered Golden Poison Frog is intelligent and captive terribilis can recognize human caregivers after exposure of a few weeks. The Black-legged Dart Frog is the second most toxic of the wild dart frogs.
Frogs of Panama
The Frogs of Panama exhibit contains the offspring of frogs rescued from an outbreak of the insidious amphibian chytrid fungus in the highlands of central Panama in 2005.
The four species that can be seen are the Crowned Tree Frog (Anotheca spinosa), Green Spiny Toad (Incilius coniferus), Pratt’s Rocket Frog (Colostethus pratti), and Gaige’s Rain Frog (Pristimantis gaigeae). Be sure to look very closely among the rocks and plants to find these sometimes secretive frogs. The exhibit also contains plants native to the Republic of Panama.
Fringed Leaf Frogs
Fringed Leaf Frogs (Cruziohyla craspedopus) are an Amazonian rainforest species from western South America. In the wild, these frogs are so hard to find that for years they eluded some of the world’s most distinguished herpetologists. Very little is known about Fringed Leaf Frogs because they live high in the tree canopy and rarely, if ever, come to the ground.
This species lays their eggs not in the water like typical frogs, but on leaves hanging over pools. The tadpoles then drop into the water upon hatching. The Garden is working toward successfully breeding them in captivity and contributing to the overall knowledge of their reproductive requirements.
