Puerto Rican Crested Toad
Peltophryne lemur
Physical Characteristics
- These toads have textured, pebbled skin and striking marbled golden eyes. The males are
olive green and gold, and the females are dull brown. The females also have rougher skin
and a high crest above the eyes.
- Size of average adult
- length: male = 3 inches, female = 4 inches
Diet
- Wild: insects, worms, insect larvae and other invertebrates
Behavior
- Nocturnal (active at night)
- Reproduction:
- heavy rains prompt breeding
- females lay as many as 15,000 eggs in long, black strands
- eggs hatch into toadlets in 18 days
- toadlets clump together to save body moisture as they move away from breeding ponds
- due to loss of breeding ponds the northern population only has been observed breeding in
walk-in concrete cattle troughs
Environmental/Global
- Habitat: drier, semi-arid regions, rocky limestone areas rain pools for breeding
- Distribution: Puerto Rico (only native toad species)- NW and SW coasts (once ranged over
entire island at lower elevation)
- Numbers:
- wild: few hundred (difficult to estimate)
- captive: 150 toads
- Status: Threatened
- habitat loss: dense human populations
- competition: proliferation of giant marine toad introduced in the 1920's to control
sugar cane grubs, compete with toad for food, habitat and spawning sites
Conservation Efforts
- Thought to be extinct until 1967
- 6 captured for captive breeding program in 1982 with release of toadlets & tadpoles
- First amphibian SSP program
- Search for areas for more natural or man-made ponds into which captive-bred can be
released or wild can be transferred
Research and Investigation Programs
- Genetic research into the difference between northern & southern populations of wild
toads
- Development of permanent marking system for identifying individuals
- Prevention of disease
- Calcium absorption by toads
- Metro Toronto Zoo developed for distribution a Spanish language poster
