WebJan 1, 2024 · The discovery of the source of toothed whale biosonar signals (echolocation clicks) started with dolphins. In the 1960s, some researchers believed that the larynx was the most likely location of sound production by dolphins because most of the other mammals used the larynx for vocalizations.
