In addition, vocalizing muscles can make up 15% of a male spring peeper's body mass, while the same muscles are only 3% of females. Frogs produce sound from the air sac below their mouth that from the outside, is seen to inflate and deflate. Air from the lungs is channeled to the air sac, which resonates to make the sound louder.
Frogs have a highly developed nervous system that consists of a brain, spinal cord and nerves. Many parts of frog brains correspond with those of humans. It consists of two olfactory lobes, two cerebral hemispheres, a pineal body, two optic lobes, a cerebellum and a medulla oblongata.

In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. [2] It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects.
The discovery of the new amphibian species could provide some answers to how frogs and salamanders evolved to get their special characteristics today, the authors wrote in the paper.
Darwin’s frog has been shown to have distinct mating patterns based on population and body size. More research needs to be conducted in order to further explore the mating of R. darwinii. [11] Most green individuals are brooding males [12] However, no brooding males have been observed copulating with females.
