Although the San Diego Zoo began in 1916, we had no frogs at all until 1968. Today, the Zoo has a new reptile, amphibian, and California native species area called Reptile Walk, which opened in July 2012. The new exhibits gives guests the opportunity to view tiny poison frogs as well as other wonderfully unique amphibians up close.
The Zoo currently has green and black poison frogs, dyeing poison frogs, splash back poison frogs, and black-legged poison frogs on exhibit in Reptile Walk. Hop on over to see them!

Can you imagine are world without frogs? While some poison frog populations are considered stable, their populations aren’t large, and their habitats are rapidly shrinking. These fascinating and beautiful little frogs are threatened by loss of their rain forest habitat and by over-collection for the pet trade. The blue poison frog has become a very popular pet in the U.S., due to its dramatic coloring. Thousands have been smuggled into pet shops all over the world, causing a swift decline in the wild population.
Another major threat to these tiny frogs is disease. One of those diseases is called chytrid fungus. It grows on the skin of adult frogs and essentially suffocates them, because they’re unable to absorb water and oxygen through their skin. San Diego Zoo Global’s scientists have been working with other scientists to survey and document the impact of chytrid in Panama. So far, they have not found that poison frogs are greatly impacted by the fungus. However, it is spreading to new areas and at some point, the poison frogs may need rescuing, too.
Biologists consider frogs to be one of the major “canaries in the coal mine,” as frogs are extremely sensitive to small changes in their environment. Disappearing species are good indicators to researchers that climate change is having an effect on the Earth’s ecology.
