Scientists have discovered 14 new species of so-called dancing frogs in the jungle mountains of southern India.

Only the males dance - it's actually a unique breeding behaviour called foot-flagging. They stretch, extend and whip their legs out to the side to draw the attention of females who might have trouble hearing mating croaks over the sound of water flowing through perennial hill streams.

The bigger the frog, the more they dance. They also use those leg extensions to smack away other males - an important feature considering the sex ratio for the amphibians is usually around 100 males to one female.
