Tiny Brazilian frogs deaf to their own calls

2 posts in this topic

Pumpkin toadlets, found on the leaf litter of Brazil's Atlantic forest, are among the smallest frogs in the world. An international team from Brazil, Denmark and the United Kingdom, has discovered that two species of these tiny orange frogs cannot hear the sound of their own calls. Their results are reported in Scientific Reports and represent a unique case of a communication signal persisting even after the target audience has lost the ability to detect it.

"We have never seen this before. These frogs make sounds that they cannot hear themselves," says Associate Professor Jakob Christensen-Dalsgaard of the University of Southern Denmark.
