Nashville Zoo recently shipped over 4,400 critically endangered Puerto Rican crested tadpoles to Puerto Rico as part of a conservation effort that releases the tadpoles into protected ponds in the Guanica National Forest. Nashville Zoo, Toronto Zoo and San Antonio Zoo sent a total of 5,742 tadpoles for release at the Gabias' Farm in Coamo, Puerto Rico on May 8. Of these 5,742 tadpoles, 4,492 were sent from Nashville Zoo.

Known for its distinctive snout and bony head crest, the Puerto Rican Crested Toad is critically endangered with only one remaining Wild population in the Guanica National Forest in the southern part of the island. In an effort to save the species from extinction, the Association of Zoos and Aquariums (AZA) created a Species Survival Plan (SSP) that focuses on research, habitat protection, citizen education and outreach, and a viable reintroduction program. Through the SSP, AZA institutions have sent 263,575 tadpoles bred at zoos and aquariums in North America to be reintroduced into the wild Nashville Zoo has been working to breed the Puerto Rican Crested Toad since acquiring the species in 2008, but was not successful until 2012 with the introduction of a hormone cocktail called Amphiplex.

Adult Puerto Rican Crested Toads can be seen in the Unseen New World as part of the Amphibians in Crisis exhibits.
