Marine mammal vocalizations occupy specific frequency ranges
Marine mammal vocalizations are categorized into distinct types, such as whistles, clicks, and pulses, which occupy specific frequency and acoustic niches.
The retrieved papers provide strong empirical evidence that marine mammals produce diverse vocalizations (such as echolocation clicks, whistles, burst pulses, and specific seal calls) that exhibit distinguishable acoustic features and occupy distinct frequency niches within their repertoires.

Long‐term passive acoustics to assess spatial and temporal vocalization patterns of Atlantic common bottlenose dolphins (<scp><i>Tursiops truncatus</i></scp>) in the May River estuary, South Carolina. 2021. https://doi.org/10.1111/mms.12800
This study distinguishes specific vocalization types such as echolocation, burst pulse sounds, and whistles in bottlenose dolphins, reflecting distinct acoustic categories.
