ABSTRACT 1 The significance of killer whale Orcinus orca predation on baleen whales
(Mysticeti) has been a topic of considerable discussion and debate in recent years …

Biopsy techniques have been developed to collect skin and blubber samples through non‐
lethal methods. One sample can provide data on genetics, prey preferences, foraging …

Anthropogenic noise may significantly impact exposed marine mammals. This work studied
the vocalization response of endangered blue whales to anthropogenic noise sources in the …

Reports of killer whales (Orcinus orca) preying on large whales have been relatively rare,
and the ecological significance of these attacks is controversial. Here we report on …

Humpback whales (Megaptera novaeangliae) are known to interfere with attacking killer
whales (Orcinus orca). To investigate why, we reviewed accounts of 115 interactions …

Population genetic structure of North Atlantic killer whale samples was resolved from
differences in allele frequencies of 17 microsatellite loci, mtDNA control region haplotype …

Studies have shown that killer whale (Orcinus orca) communities in high latitudes regularly
comprise assemblages of sympatric 'ecotypes'—forms that differ in morphology, behavior …

Killer whales (Orcinus orca) are apex marine predators, having been documented preying
upon nearly every large animal species that swims in the ocean (Ford, 2019; Jefferson et al …

Each individual cetacean is an ecosystem itself, potentially harboring a great variety of
animals that travel with it. Despite being often despised or overlooked, many of these …

Many aspects of blue whale biology are poorly understood. Some of the gaps in our
knowledge, such as those regarding their basic taxonomy and seasonal movements, directly …
