Frogs are amphibians.
They spend their lives both in the water and on dry land. Beginning life as eggs floating on the surface of still waters, they develop into swimming tadpoles, eventually changing completely, becoming frogs. These major changes in form occur under the control of hormones, which are chemical messengers that travel throughout the organism, turning on and off bodily processes. So far, they say, they believe inherited genetic mutations are not involved. This would mean the deformities are being caused by something that affects the frogs during early life, when they are eggs or tadpoles.
