The endangered Puerto Rican crested toad (Peltophryne lemur), like many amphibians world wide, is in critical danger of extinction. These toads are unique and easily identified by their turned up snout and bony head crest. Females are larger than 4 inches and weigh 3-6 ounces, while males are smaller than 3 inches and weigh about 2 ounces. Photographed at the Nashville Zoo, Nashville, TN.
Crested toads live in low lying areas with rocky crevices or well-drained soil. Toads mate in seasonal pools called leks formed during the rainy season and have up to two years between breeding based on rainfall patterns.
The greatest threats affecting the Puerto Rican crested toad are human-related and include habitat loss and the introduction of the invasive giant toad (Rhinella marinus). The wild population fluctuates between 1,000-3,000 adult toads, all of which are found in Guánica National Forest on the southern coast.
