The Society for Marine Mammalogy declined to recognize the two species, citing uncertainty as to whether the types constituted unique species or subspecies. "Pending a more complete global review and revision", the Society provisionally recognized them as subspecies Orcinus orca ater and O. o. rectipinnus, with O. o. orca as the nominate ...
The IUCN reported in 2008, "The taxonomy of this genus is clearly in need of review, and it is likely that O. orca will be split into a number of different species or at least subspecies over the next few years." [3] However, large variation in the ecological distinctiveness of different orca groups complicate simple differentiation into types. [4]
The research vessel Noctiluca of the Northwest Fisheries Science Center in close proximity to an orca. The southern resident orcas, also known as the southern resident killer whales (SRKW), are the smallest of four communities of the exclusively fish-eating ecotype of orca in the northeast Pacific Ocean.
Northern resident orcas, also known as northern resident killer whales (NRKW), are one of four separate, non-interbreeding communities of the exclusively fish-eating ecotype of orca in the northeast portion of the North Pacific Ocean.
We know that orcas are highly intelligent and highly tuned into each other. So very clearly, she would’ve been aware that her daughter had died and was not going to revive.
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.
Orca vs. whale shark. The researchers’ analysis revealed exactly how the killer whales, often hunting as a group, subdue the whale shark. First, the orcas use their bodies to hit a whale shark ...
It was an orca-versus-dolphin matchup, and the dolphin didn’t stand a chance. In coastal waters near Chile in 2023, a massive female killer whale walloped the much smaller dolphin, sending it ...
