The southern resident pod is their normal traveling unit. The three southern resident pods form the single clan of this small killer whale community. The clan is possibly a single lineage that split into pods in the past. The clan has a unique stable dialect that shares no calls with other killer whale clans. [14]
The orca lineage probably branched off shortly thereafter. [17] Although it has morphological similarities with the false killer whale, the pygmy killer whale and the pilot whales, a study of cytochrome b gene sequences indicates that its closest extant relatives are the snubfin dolphins of the genus Orcaella. [18]
The northern resident population consists of three clans (A, G, R) that consists of several pods with one or more matrilines within each pod. The northern residents are genetically distinct from the southern resident orcas and their calls are also quite distinct.
An endangered orca vanished from a dwindling whale pod off the Washington coast, a conservation group said. The missing Southern Resident killer whale, K-26, was not seen by researchers during an ...
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]
Tahlequah (born c. 1998), also known as J35, is an orca of the southern resident community in the northeastern Pacific Ocean. She has given birth to four known offspring, a male (J47 "Notch") in 2010, a female (Tali) in 2018, another male (J57 "Phoenix") in 2020, and another female (J61) in 2024.
An orca pod in the Pacific Ocean off the coast of Mexico has devised a cunning strategy to hunt and kill whale sharks — the world’s largest fish that can grow up to 18 meters (60 feet) in ...
