Insult to Injury: Population Impacts of Sublethal Entanglement and Vessel Strikes of Common Bottlenose Dolphins (Tursiops truncatus) in Barataria Basin, Louisiana, 2011–2023

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Human interactions, specifically fishery entanglements (FI) and vessel strikes (VI), threaten marine mammals, including the Barataria Bay Estuarine System (BBE) Stock of common bottlenose dolphins (Tursiops truncatus). We reviewed whole‐body photographs to estimate the prevalence of sublethal entanglement and vessel strike scars for 227 ...

Molecular ecology of Bottlenose (Tursiops sp.) and common (Delphinus sp.) Dolphins [PDF]

, 2004
Bottlenose (Tursiops sp.) and common dolphins (Delphinus sp.) are amongst the most common small cetaceans. They both have a world-wide distribution from warm temperate to tropical waters inhabiting pelagic and coastal waters, and they both show high ...

First record of a white rough-toothed dolphin (Steno bredanensis) off West Africa including notes on rough-toothed dolphin surface behaviour [PDF]

, 2010
In June 2009, a white rough-toothed dolphin (Steno bredanensis) calf was photographed in a group of at least 50 dolphins in the southern Gulf of Guinea, 95 nauticol miles off the Gabon coast (01°45'S 007°29'E), West Africa. Reports of unusually pigmented

A Robust Design Capture-Recapture Analysis of Abundance, Survival and Temporary Emigration of Three Odontocete Species in the Gulf of Corinth, Greece.

PLoS ONE, 2016
While the Mediterranean Sea has been designated as a Global Biodiversity Hotspot, assessments of cetacean population abundance are lacking for large portions of the region, particularly in the southern and eastern basins.

Structural Variation in Whistle Patterns of Two Coastal Dolphin Species Co‐Occurring in the Southern Israeli Mediterranean Sea

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Two coastal dolphin species, the common bottlenose dolphin (Tursiops truncatus—Tt) and the short‐beaked common dolphin (Delphinus delphis—Dd), co‐occur along the southern Israeli Mediterranean coast, where the critically endangered Dd population faces ecological pressures, potentially including competitive exclusion by that of the Tt ...

Group‐Specific Variation in Heterodyne Frequencies of Biphonic Calls in Resident (R‐Type) Killer Whales Orcinus orca ater

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Biphonation—the simultaneous production of two independent fundamental frequencies within a single vocalization—is a prominent feature of killer whale calls, yet the factors influencing the presence and intensity of heterodyne frequencies, which arise from interactions between these fundamentals, remain poorly understood. We analyzed long‐term

Mind the Gap: Performance Limits of Automated Contour Extraction Methods for Individual Monitoring of Bottlenose Dolphins

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Reliable extraction of dolphin whistle contours is fundamental for scalable analyses of vocal identity, repertoire structure, and individual‐based acoustic monitoring. We evaluated four algorithms for fundamental frequency estimation of common bottlenose dolphin (Tursiops truncatus) whistles, leveraging a benchmark dataset of annotated ...
