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 ...

Integrating eDNA and Visual Surveys With Ocean Drift Models to Monitor Marine Mammals in Tropical Waters

Environmental DNA, Volume 7, Issue 5, September–October 2025.
This study evaluates the effectiveness of environmental DNA (eDNA) metabarcoding for monitoring marine mammals in tropical waters around Réunion Island. By combining visual surveys with eDNA sampling and reverse particle drift modeling, we show that eDNA captures local cetacean presence and offers additional spatial insight when integrated with ...

From Mechanoelectric Conversion to Tissue Regeneration: Translational Progress in Piezoelectric Materials

Advanced Materials, Volume 37, Issue 33, August 21, 2025.
This review highlights recent progress in piezoelectric materials for regenerative medicine, emphasizing their ability to convert mechanical stimuli into bioelectric signals that promote tissue repair. Key discussions cover the intrinsic piezoelectric properties of biological tissues, co‐stimulation cellular mechanisms for tissue regeneration, and ...

Morphological and genetic identification of Anisakis paggiae (Nematoda: Anisakidae) in dwarf sperm whale Kogia sima from Brazilian waters [PDF]

Diseases of Aquatic Organisms, 2015
Anisakid nematodes have been identified in a wide variety of fish and marine mammal species. In Brazil, Anisakis physeteris, A. insignis, A. typica, A. nascetti, and those of the A. simplex complex have been reported infecting fishes and cetaceans.

Gone in a Splash? Temporal Dynamics of Flukeprint Environmental DNA (eDNA) Detection for Common Coastal Northeast Pacific Cetacean Species

Environmental DNA, Volume 7, Issue 3, May–June 2025.
Environmental DNA (eDNA) techniques have been successfully used to detect cetacean species, including harbor porpoises, humpback whales, and killer whales, through direct “flukeprint” sampling. This study assessed the persistence of eDNA shed in flukeprints by collecting seawater samples at timed intervals (up to 10 min) following dives of these ...

Utilization of stable isotopes in teeth to investigate pygmy sperm whales (Kogia breviceps) in the southeastern United States

Marine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract The pygmy sperm whale (Kogia breviceps) is currently the second‐most stranded cetacean in the southeastern United States (SEUS), but information concerning their population structure is severely limited. This study used stable isotope analysis to investigate the isotopic niches and population structure of K.

Sighting of a large group of pygmy sperm whales ( Kogia breviceps ) and a recent record of a dwarf sperm whale ( K. sima ) in the Azores

Journal of the Marine Biological Association of the United Kingdom
Abstract The family Kogiidae, comprising the pygmy sperm whale ( Kogia breviceps ) and the dwarf sperm whale ( K. sima ), represents some of the least-known cetaceans worldwide.

Validated Environmental DNA Assay for Detection of the Rare Rice's Whale (Balaenoptera ricei)

Environmental DNA, Volume 7, Issue 2, March/April 2025.
The first eDNA assay was developed to detect the presence of the Rice's whale from environmental samples. This validated qPCR assay is highly sensitive and species‐specific and can be utilized in future studies to better understand the temporal and spatial distribution of this rare and endangered species.

Evidence of marine predation on silver New Zealand longfin eels, Anguilla dieffenbachii

Fisheries Management and Ecology, Volume 31, Issue 4, August 2024.
Abstract The use of Pop‐up Satellite Archival Tags (PSATs) has provided considerable new information about the behaviour of migrating (silver) eels (Anguilla spp.) at sea, with 9 of 19 recognised species or subspecies tagged to date. However, such studies often reported premature tag detachment and relatively high rates of predation.
