Frog Deformities
Biologists have been puzzled by the apparent epidemic of frog limb deformities seen in Canada and the United States. Researchers are studying the role of things like pollution, diseases, and changes in the environment.
More about Frogs
Frogs are very sensitive to pollution around them. Things that can hurt frogs include fertilizers, weed killers, pesticides, and detergents. This is because they breathe and absorb water through their skin. The chemicals can easily enter their bodies through the skin.
Frog eggs and tadpoles are even more sensitive than adult frogs. They can be exposed to pollution in the water they live in.
