This critically endangered little brown toad lives in the rocky arid evergreen forests. The Puerto Rican crested toad is bred at Cleveland Metroparks Zoo for reintroduction of the tadpoles back in Puerto Rico.
This is a small toad (2-4 inches long), with the female being the larger of the two sexes. Coloration is brown marbled with a yellowish-tan or white color, and darker raised lumps along the back and legs. Males show more yellow than females on their back. Females are larger than males, and more robust. They have horny ridges on their head and their toes are webbed.
Threats: habitat loss
The Zoo is protecting amphibians in partnership with Amphibian Ark.
Cleveland Metroparks Zoo is working to secure a future for the Puerto Rican crested toad by breeding these toads here and sending the tadpoles to Puerto Rico, where they finish their morph into toads.
They are a nocturnal terrestrial species that live in excavated burrows and semi-arid rocky areas in evergreen forests.
They use seasonal ponds during the rainy season to reproduce, and return to the rocky limestone areas after laying their eggs in long black strings. It takes about 18 days for the eggs to mature into toadlets in the wild. Even though reproduction is sporadic it occurs throughout the year.
