Comparative Analysis of the Whistles of Three Oceanic Dolphins in the Comoros

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT The Shisiwani National Park (Anjouan, Comoros) is a cetacean biodiversity hotspot. However, the vocal behavior of marine mammals inhabiting the area has never been studied. In 2023, we conducted a 400‐nautical‐mile survey from a 5‐m motorboat to determine their presence.

Melon‐Headed Whale (Peponocephala electra) Occurrence in the Equatorial Mid‐Atlantic Ocean With Descriptions of Their Whistles

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Acoustic studies for any cetacean species in tropical Atlantic Ocean waters are scarce, especially for oceanic dolphins, such as the melon‐headed whale, Peponocephala electra. Here we describe a unique visual and acoustic record for this species, filling an information gap about the acoustic patterns of these delphinids in this part of the ...

A Detailed Characterization of the Whistle Repertoire of Fraser's Dolphins (Lagenodelphis hosei) From the Lesser Antilles

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Fraser's dolphin (Lagenodelphis hosei) remains poorly studied due to its elusive behavior, rarity, and preference for deep offshore habitats. While dolphins use frequency‐modulated whistles for communication, detailed acoustic descriptions exist for only a few species.

Portable Molecular Diagnostics for Cetacean Morbillivirus: Development of a Reverse Transcription Insulated Isothermal PCR (RT‐iiPCR) for Global Surveillance

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Cetacean morbillivirus (CeMV) drives recurrent unusual‐mortality events, yet surveillance is uneven where laboratory capacity is limited. We developed a portable reverse transcription‐insulated isothermal PCR (RT‐iiPCR) assay targeting a conserved phosphoprotein (P)‐gene segment and evaluated analytical performance, tissue‐level clinical sensitivity ...
