Distribution and Habitat

The only toad native to Puerto Rico, this species is confined to that island's Guanica National Forest, where it can be found in dry, semi-arid regions around pool areas, vegetated offshore islands, cliffs, rock outcrops, etc.


The Puerto Rican crested toad feeds on insects, worms, larvae, and other invertebrates.


Breeding usually follows heavy rains, after which up to 15,000 eggs are laid in long, black strands. Toadlets hatch in 18 days, and then clump together to save body moisture as they move away from breeding ponds.

Habits and Behaviors

Crested toads are solitary and nocturnal.

Conservation Status

The Puerto Rican Crested Toad was thought to be extinct until 1967. Now an endangered species, there are only a few hundred left in the wild, and only about 150 in captivity. The decline of this species is due primarily to increasing human populations, as well as to the introduction of the giant marine toad, which competes for food and breeding sites.
