Comparative Anatomy of the Larynx in Pinnipeds (Seal, Sea lion, Walrus)
Pinnipeds (e.g., seal, sea lion, walrus) are marine mammals that spend time both in and out of the water. All are able to vocalize in air using the pneumatically driven vocal fold vibrations, a mechanism common to terrestrial mammals. This is no surprise, as their ancestors were once terrestrial mam...

Pinnipeds (e.g., seal, sea lion, walrus) are marine mammals that spend time both in and out of the water.
