Walruses have vocal cords.

Walruses produce sounds both above and below water.

Walruses are among the most vocal of the pinnipeds. They produce growls, taps, knocks, grunts, barks, soft whistles, rasps, and clicks.

Male walruses produce bell-like sounds below water. These sounds are not produced by the vocal cords but originate from air sacs, which extend from the pharynx.

Calves bellow if disturbed.

Walruses communicate through auditory and visual displays.

During courtship, males display visually and vocally from the water. Stereotyped sequences of sounds occur both above and below water. Underwater sounds include clicks or knocks, bell-like sounds, and taps. Above-water sounds include teeth clacking and whistles. Courtship displays continue until a female physically contacts a displaying male in the water.

Males engage in tusk-threat displays to establish dominance.

Walruses communicate through sound, sight, touch, and smell.

Tactile communication occurs through body contact.
