Frogs are amphibians and are able to live both underwater and on land. In order to do this they have very special skin; the skin of the frog produces a kind of oil for protection, as an ointment, in fact for many reasons.
This oil contains some very interesting and rare chemicals, some of which have been used for medical purposes.
This micro frog was recently found in Indonesia, on the island of Borneo. Even though it is small it makes a loud croak (that’s how it was found).
Frogs are very important animals.
