At the time, orcas were not only viewed as costly competition with fishermen ...
Orcas, like this one near Alaska, commonly breach, often lifting their entire bodies out of the water. Day-to-day orca behaviour generally consists of foraging , travelling, resting and socializing. Orcas frequently engage in surface behaviour such as breaching (jumping completely out of the water) and tail-slapping.
They have mostly been encountered off the west coast of Vancouver Island and near Haida Gwaii. Offshores typically congregate in groups of 20–75, with occasional sightings of larger groups of up to 200. [27] Little is known about their habits, but they are genetically distinct from residents and transients.
While many chemicals can be found in the tissues of orca, the most common are the insecticide DDT, polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs). [116] Each of these have detrimental physiological effects on orca, [ 117 ] and can be found in such high concentrations in dead individuals that those individuals must ...

An orca breaching in Hood Canal. The marine mammals of the Salish Sea are numerous and diverse, both in taxonomy and morphology. A total of six species of pinnipeds, eight species of baleen whales, seventeen species of toothed whales, and one mustelid (the sea otter) inhabiting the local waters of the Salish Sea and the outer coastal waters over the continental shelf off Washington and British ...
“The reality blew our minds,” the boaters said of the sighting in Norway.
Killer whales are among the most well-known cosmopolitan species on the planet, as they maintain several different resident and transient (migratory) populations in every major oceanic body on Earth, from the Arctic Circle to Antarctica and every coastal and open-water region in-between.
