Frogs and toads are one of the most common species of amphibians. They are found not only in the wetlands, but all over the world. The young go through a larval stage in the water. During these stages they lose their gills and grow webbed feet. Much of their reproductive qualities vary with respect to their specific species.
Frogs often consume insects and lay eggs to produce young.
A concern held by many environmentalists is that many amphibian populations are declining in a number of geographical locations throughout the world. In most cases, the changes are assumed to result from man-made alteration in the environment.
