Frogs have a body surrounded by a skin with some unusual properties. It holds the tissues and fluids in just like our skin but it is also porous, allowing both air and water to pass directly through it. In fact, frogs do not drink water through their mouths at all - it is absorbed through the skin on their lower abdomen. Because of this porous skin which allows water to pass directly into the body cavity without being filtered through the stomach, frogs are susceptible to any and all pollutants in the environment. This is why frogs are so often referred to as 'environmental indicators' - which is a more formal way of saying that they are our 'canaries in the coal mine'.
Aside from telling us when there is something
wrong in our environment, frogs' skin also has some unusual chemical properties of it's own. For example, many species have anti-fungal agents in their skin which help to protect them from fungus attack in the wet and humid habitats they live in. Some of these skin properties are being studied by Prof. Mike Tyler at the University of Adelaide in South Australia and he has reportedly made some discoveries which are of medical benefit to people.I have found a great little quiz and it will inform you about What Kind of Frog you are.

African Dwarf Frogs are social creatures. They like to swim all day in warm water (76-78*F) and make excellent pets for beginners because they don't require live crickets for food! They eat frozen bloodworms or brine shrimp. What kind of Frog are you?
Meet you all down at the pool!
