Stable Isotope Analysis (δ13C and δ15N) of Baleen Plates Reveals Feeding Patterns in Stranded Humpback Whales (Megaptera novaeangliae) Along the Brazilian Coast

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Humpback whales (Megaptera novaeangliae) from breeding stock A migrate annually between Antarctic feeding grounds (~65° S) and Brazilian breeding areas (~17° S). Traditionally considered to fast during migration, recent feeding observations and increased strandings along southeastern Brazil (~23° S) raise questions about possible shifts in ...

Total Numbers and Movements of Photo‐Identified Subantarctic (Type D) Killer Whales

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The distinctive Subantarctic (Type D) killer whale (DKW) (Orcinus orca) is a highly divergent and apparently inbred form previously known only from three mass strandings and several dozen at‐sea sightings, primarily from Patagonian toothfish (Dissostichus eleginoides) longline vessels in the southern Indian Ocean and from tourism vessels in ...

Blubber Cellular Integrity Through Decomposition and Its Implication for Histological Applications: A Study of Stranded Stock A Humpback Whales (Megaptera novaeangliae)

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Marine mammal strandings can provide unique and valuable insights into individual and population health, ranging from infectious diseases to anthropogenic threats. However, the level of decomposition of carcasses can interfere with the assessment of important indicators, such as an individual's nutritional status.

Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...

Dwarf Minke Whale (Balaenoptera acutorostrata) Mother and Calf Ecology in East and Southern Australia

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Knowledge of mother–calf pairs, migratory patterns, female reproductive cycles, and birth‐year calf development are all essential for understanding risks in these critical life stages and monitoring little‐known dwarf minke whale (Balaenoptera acutorostrata) populations.
