Why Frogs Are ImportantWe can get new medicines from frogs that can save lives!
Frogs are bio-indicators, if they are around you can tell how well the environment is faring.Frogs are an important part of the food chain: They eat animals and animals eat them.
This is a yellow poisonous dart frog. Their poisonous skin secretions can be used for medicine which may be able to be used to prevent heart attacks.Slide3
What Harms ThemClimate change can affect their habitat.Pollution makes their natural habitat unfit for them, and they can absorb harmful substances into their skin.
UV radiation can damage their sensitive skinFungal skin infections can be fatal to frogsOveractive predators eat too many frogs, in fact humans are overharvesting and eating frogs!Parasites are causing frogs to become ill.
