Species Profiles

Documenting the vocal characteristics, acoustic repertoires, and conservation contexts of studied species in bioacoustic and animal communication research.

Stenella frontalisLeast Concern

Atlantic Spotted Dolphin

Delphinid species native to warm temperate and tropical waters of the Atlantic, studied in long-term non-invasive field research for its social behavior and acoustic repertoire. Classified globally as Least Concern by the IUCN Red List (Braulik & Jefferson, 2018; DOI: 10.2305/IUCN.UK.2018-2.RLTS.T20732A50375312.en), having previously been assessed as Data Deficient.

Acoustic Profile: Frequency-modulated whistles (fundamental frequencies typically 4–18 kHz, with harmonics extending beyond 50–100 kHz), ultrasonic echolocation clicks (bimodal spectral peaks at 40–50 kHz and 110–130 kHz), and burst-pulsed packets.

Tursiops truncatusLeast Concern

Common Bottlenose Dolphin

Widely distributed coastal and pelagic odontocete whose individually distinctive signature whistle repertoire has been extensively documented across decades of bioacoustic research.

Acoustic Profile: Individually distinctive signature whistles (typically 4–24 kHz), broadband echolocation click trains (peaking up to 110–130 kHz), and burst-pulsed sounds.

Megaptera novaeangliaeLeast Concern

Humpback Whale

Baleen whale famous for complex, hierarchically structured songs produced primarily by males during breeding migrations.

Acoustic Profile: Evolving multi-theme songs (30 Hz–8 kHz), feeding calls, and surface impact slaps.

Taxon: CetaceaView Humpback Whale profile

Physeter macrocephalusVulnerable

Sperm Whale

Deep-diving toothed whale communicating via stereotyped rhythmic click patterns termed codas, organized into distinct vocal clans.

Acoustic Profile: Slow clicks for foraging, regular rhythmic codas for social identity.
