Feeding 11-ketotestosterone coated scallops to toadfish increases their calling behavior, [7] which identifies 11-ketotestosterone, an androgen hormone, as a mediator of midshipman fish vocalization. There are also high levels of aromatase, an estrogen-generating enzyme, in the hindbrain vocal motor region. Estradiol steroids and their ...
Toothed whale (odontocete) vocal anatomy. Most mammalian species produce sound by passing air from the lungs across the larynx, vibrating the vocal folds. [3] Sound then enters the supralaryngeal vocal tract, which can be adjusted to produce various changes in sound output, providing refinement of vocalizations. [3]
