Once the stocks of larger species were depleted, orcas were targeted by commercial whalers in the mid-20th century. Between 1954 and 1997, Japan took 1,178 orcas (although the Ministry of the Environment claims that there had been domestic catches of about 1,600 whales between late 1940s to 1960s [214]) and Norway took 987.

Type D or Sub-Antarctic [4] orcas were first identified based on photographs of a 1955 mass stranding in New Zealand and six at-sea sightings since 2004. The first video record of this type was made in 2014 between the Kerguelen and Crozet Islands, [61] and again in 2017 off the coast of Cape Horn, Chile. [62]
'They were harassed, shot at, and killed at every opportunity. ' " [1] Don White, once an orca researcher at the Vancouver Aquarium, later a critic of orca captivity, wrote in 1975, "Before the capture of Moby Doll, of Namu and of Skana killer whales as a species were regarded by fishermen as vermin.

They soon became popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness in captivity and sheer size. [1]
Scientists saw a male orca kill a juvenile great white shark within minutes last year. The hunting behavior could be a sign of a wider shift in the marine ecosystem.
The genus Orcinus was published by Leopold Fitzinger in 1860, [4] its type species is the orca named by Linnaeus in 1758 as Delphinus orca.Taxonomic arrangements of delphinids published by workers before and after Fitzinger, such as John Edward Gray as Orca in 1846 and Orca (Gladiator) in 1870, are recognized as synonyms of Orcinus.
Approving two proposed killer whale species could transform how they're conserved. It would also turn a new page in one of the strangest chapters in marine mammal history.
A vampire hedgehog, a pygmy pipehorse and a "blob-headed" fish were among the hundreds of new species identified in 2024. The variety of species identified was quite eclectic and names for the new ...
