Scientists in the jungles of southern India have discovered 14 new species of "dancing frogs" many of which are unfortunately already endangered. DNA analyses have shown that these new species are members of an ancient genus that has been around since the time of the dinosaurs, Micrixalus. There are now 24 known species of dancing frogs. Considering that males outnumber females 100 to 1, these acrobatics are important to attract mates. The tiny frogs are only about the size of a walnut.
