What are the specific sounds walruses produce when communicating underwater?

Answer

Clicks, whistles, and bell-like notes

Walruses possess a complex auditory repertoire, utilizing different sounds for communication both above and below the water surface. Underwater, their acoustic signaling includes a distinct set of sounds described as clicks, whistles, and notes resembling bells. These underwater vocalizations are critical for internal group coordination and are also believed to play a role in locating potential mates in the often dark or murky aquatic environment. Above the surface, however, social interactions and dominance displays are typically accompanied by much louder audible sounds, such as grunts and roaring noises.
