Correlates of variability in killer whale stereotyped call repertoires. [PDF]

, 2005
Killer whales vocalisations include repertoires of stereotyped call types (Ford 1984). There is strong evidence that these vocalisations are learnt (Hoelzel and Osborne 1986; Bain 1989; Deecke et al. 2000; Yurk et al. 2002).

Experimental evidence for action imitation in killer whales (Orcinus orca)

, 2012
Comparative experimental studies of imitative learning have focused mainly on primates and birds. However, cetaceans are promising candidates to display imitative learning as they have evolved in socioecological settings that have selected for large ...

The impact of predation by marine mammals on patagonian toothfish longline fisheries.

PLoS ONE, 2015
Predatory interaction of marine mammals with longline fisheries is observed globally, leading to partial or complete loss of the catch and in some parts of the world to considerable financial loss.

Vertebral bone microarchitecture and osteocyte characteristics of three toothed whale species with varying diving behaviour

Scientific Reports, 2017
Although vertebral bone microarchitecture has been studied in various tetrapods, limited quantitative data are available on the structural and compositional changes of vertebrae in marine mammals. Whales exhibit exceptional swimming and diving behaviour,

First record of orcas (Orcinus orca) preying on a prickly shark (Echinorhinus cookei) in the Gulf of California: insights into shark ecology

Frontiers in Fish Science
The first documented instance of predation on a prickly shark (Echinorhinus cookei) by orcas (Orcinus orca) in the shallow waters of the southwestern Gulf of California, particularly around Cerralvo Island, is presented. The observation was made possible

Vocal activity as a welfare indicator in killer whales in managed care

Frontiers in Marine Science
IntroductionMonitoring acoustic activity is a promising approach for assessing animal welfare in cetaceans. In particular, variations in vocal production may reflect changes in arousal and emotional state, which are critical components of welfare ...

Tongue Nibbling in Killer Whales (Orcinus orca)

This dataset comprises high-definition video recordings documenting tongue-nibbling behaviour in killer whales (Orcinus orca) observed both under human care at Loro Parque (Orca Ocean, Tenerife, Spain) and in a wild population off the coast of northern ...

A global review of operational fishery interactions with killer whales (Orcinus orca): dynamics, impacts, and management strategies

Frontiers in Marine Science
Killer whales (Orcinus orca) are cosmopolitan, apex predators that sometimes interact with commercial fisheries. These fishery interactions can affect killer whales, sometimes harmfully, and cause negative socioeconomic consequences for the fishing ...
