You may not think frogs are pioneers in environmental protection, but Brandon barengi, an American biologist and artist, uses the deformities found in wild amphibians to highlight the damage we are doing to our earth home.
Some frogs, including this Pacific tree frog from California, USA, grow extra limbs due to mutation rather than less
The nymphs of dragonflies feed on tadpoles and cause the growth of limbs of these victims to change, resulting in deformed frogs
A deformed toad found in Yorkshire, England, lacks some limbs, which may be caused by chemical pollution
A North American green frog caught in New York, USA, lacks some limbs, which may be caused by chemical pollution
Scientists believe that frogs become more susceptible to parasites as a result of chemical interventions
