Cornufer vitianus
There are fewer of this frog than there were.  This is because human beings change the places where the frog lives and because of other animals that want to eat it.  Some of these animals have lived in the Fiji islands for a long time.  Others came there because humans brought them.  The most important predators are the mongoose, rat, cat, and cane toad.  Now, this frog only lives on islands where there are no mongoose.
