I read in the paper that frogs and toads are becoming scarce and that many of them have extra legs and other deformities. Is this a sign of disease that is causing them to die?
Declines in several amphibian species have been studied for over 20 years.
There does not appear to be one 'smoking gun'; numerous environmental factors are probably responsible for the declines and deformities.
Multiple limbs, missing limbs, and facial abnormalities are the main developmental malformations seen.
In response to indications of worldwide declines in amphibian populations, the President and Congress directed Interior Department agencies to initiate a national program of amphibian monitoring, research, and conservation.
