Kogia Records in Brazilian Equatorial and Southwestern Atlantic Oceans

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales are cryptic cetaceans characterized by inconspicuous surfacing behavior, small group sizes, and deep‐diving habits, making visual detection particularly challenging. Here, we present the first broad‐scale passive acoustic monitoring (PAM) assessment of Kogia spp.

High-resolution biologging of an Atlantic bluefin tuna captured and eaten by a supposed orca

Scientific Reports
Biologging has been used on a range of wild animals to document spectacular feats of migration and behaviour. We describe the pursuit, capture, and ingestion of an adult Atlantic bluefin tuna (Thunnus thynnus) (175 cm, estimated weight: 81 kg), which was

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
