🐸 Frogs produce two types of calls that most experiments tend to focus on, which are "release calling" and "mating calling." Only the male frogs can produce mating calls to attract gravid female frogs. When male and non-gravid female frogs are clasped by sexually active male frogs, they produce a release call. In the leopard frog, there are three movements for their sound production.⁠ ⁠ First, there are body wall contractions to serve as a way for the intrapulmonary pressure to increase. Second, for airflow to pass through the larynx, the glottis must be open. Third and last, in the larynx, the vocal cords must oppose each other at the midline so that the airflow can cause them to vibrate. In addition, their release calls and movements of their throats and sides are correlated with laryngeal calling movements.⁠ _____⁠ ⁠ 🧬 For the Concave-eared torrent frog, produce sounds in the ultrasonic range. Three areas that are highly involved in frog calls are the preoptic area, the medulla-mi...
