Vocalisations of Killer Whales (Orcinus orca) in the Bremer Canyon, Western Australia

To date, there has been no dedicated study in Australian waters on the acoustics of killer whales. Hence no information has been published on the sounds produced by killer whales from this region. Here we present the first acoustical analysis of recordings collected off the Western Australian coast. Underwater sounds produced by Australian killer whales were recorded during the months of Februa...

Killer Whale (Orcinus orca) Predation on Beaked Whales (Mesoplodon spp.) in the Bremer Sub-Basin, Western Australia

Observations of killer whales (Orcinus orca) feeding on the remains of beaked whales have been previously documented; however, to date, there has been no published account of killer whales actively preying upon beaked whales. This article describes the first field observations of killer whales interacting with, hunting and preying upon beaked whales (Mesoplodon spp.) on four separate occasions ...

A Review of Marine Mammal Deterrents and Their Possible Applications to Limit Killer Whale ( Orcinus orca) Predation on Steller Sea Lions (Eumetopias jubatus)

This report does not constitute a publication and is for information only. All data herein are to be considered provisional. Abstract The population of Steller sea lions (Eumetopias jubatus) in the western Aleutian Islands has declined significantly and is currently listed as an endangered species.

First longitudinal study of seal-feeding killer whales (Orcinus orca) in Norwegian coastal waters

Killer whales (Orcinus orca) have been documented preying on either fish or marine mammals in several regions, suggesting that this odontocete species has the ability to specialize on different types of prey. Off Norway, killer whales have been shown to rely on the Atlantic herring (Clupea harengus) as a main prey resource. Infrequent observations have revealed seals as an additional component ...
