A Secret Frog With a Unique Song Was Just Discovered in the Amazon Rainforest!

Experts had to listen closely and test its DNA [the tiny blueprint inside every living thing] to prove it was a brand-new species. Who knows what other incredible creatures are playing hide-and-seek in the jungle right now?
