Amphibians Unit Study
Compared to other vertebrates, amphibians tend to be overlooked. Why? Perhaps it is because they are not "warm and fuzzy" like mammals. Or could it be that they don't evoke the fear, fascination and respect that reptiles inspire? They most certainly lack the sporting appeal of fish. Many more people prefer watching birds to amphibians. Come with us today to explore the wet and wild world of amphibians.
