The Brazilian Torrent Frog has one of the most sophisticated form of communication for a frog. The male of the species will pick a mating spot, high on rocks next to a busy stream. They will try to make mating or territorial calls but the stream is very loud behind them, drowning out their calls. The frogs have adapted a way to talk to the frogs over the sounds on the stream. The male frogs will raise their feet in a circular movement and show off their white toe pads. This is called foot flagging.
The males will do it to attract females and to warn other males to leave. If the other males don’t leave, they will fight it out for the spot with the loser hopping away. If a predator was to see the foot flagging and come after the male frog, the male will jump into the stream. This is a really quick getaway.
If a female picks a male to mate with, they will approach the male. The male will continue to call. The female will then stretch one or both of her legs backwards and move one hand up and down. The male will then touch her snout with his throat. Next to male will jump around the rocks and perform more foot flagging. He then jumps into the water followed by the female.
