Stranding of a Hector's Beaked Whale (Mesoplodon hectori) (Gray 1871) From South Australia Unearths Novel Additional Teeth

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Most extant beaked whales have reduced dentition of one or two pairs of tusk‐like, mandibular teeth that erupt through the gum only in adult males. Additional teeth have been recorded in several species and genera. A juvenile Hector's beaked whale (SAMA M26434) having additional teeth was collected in South Australia and its skeleton and ...

How man-made interference might cause gas bubble emboli in deep diving whales [PDF]

, 2014
Recent cetacean mass strandings in close temporal and spatial association with sonar activity has raised the concern that anthropogenic sound may harm breath-hold diving marine mammals.

Cuvier's beaked whale (Ziphius cavirostris) detection through surface-sourced eDNA: A promising approach for monitoring deep-diving cetaceans

Ecological Indicators
Among cetaceans, the Cuvier’s beaked whale is considered an extreme diver, thus not one of the easiest cetacean species to be studied due to its elusive behaviour and a preference for deep offshore waters.

Marine mammals of Easter Island (Rapa Nui) and Salas y Gómez Island (Motu Motiro Hiva), Chile: a review and new records

Latin American Journal of Aquatic Research, 2014
The Chilean oceanic islands Easter Island (Rapa Nui) and Salas y Gómez Island (Motu Motiro Hiva) have received little attention with regards to basic marine mammal investigations.

Marine Mammals in the Anthropocene: Developing a Systematic Evidence Base of Threats to Nineteen Species

Mammal Review, Volume 56, Issue 1, March 2026.
Marine mammals are vulnerable to a variety of anthropogenic threats, yet a global systematic map of the literature for 19 species found both spatial and temporal disparity in research effort between threats and between species. There are knowledge gaps for species and threats, with effort unequal across many species' ranges.

Climate Change, Local Harvests and Marine Contamination: A Perspective on Cetacean Populations and Coastal Whaling Communities

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Cetaceans are indicators of ocean health, influence marine ecosystem dynamics and hold socio‐economic importance for coastal whaling communities. Yet whale–whaler relationships remain poorly understood and are increasingly compromised under the triple planetary crisis of climate change, biodiversity loss and pollution. Here, we briefly outline

Behavioral responses of goose‐beaked whales (Ziphius cavirostris) to simulated military sonar

Ecosphere, Volume 17, Issue 1, January 2026.
Abstract We report direct measurements of changes in diving and movement behavior for 53 goose‐beaked whales (Ziphius cavirostris) in relation to experimentally controlled mid‐frequency (3–4 kHz) active sonar (MFAS) signals. These signals simulate powerful Navy sources that have been associated with multiple mortal stranding events for this species. We
