SRKW meaning in Community ?

The southern resident killer whales (SRKW) represent the smallest of four resident communities within the northeastern portion of the North Pacific Ocean. The National Marine Fisheries Service listed this distinct population segment of killer whales as endangered, effective in 2005, under the Endangered Species Act.In Canada the SRKW are listed as endangered on Species at Risk Act Schedule 1. They are commonly referred to as the "orcas of the Salish Sea", "fish-eating orcas", "southern residents", or the "SRKW population". Unlike other resident communities, the SRKW is only one clan (J) that consists of 3 pods (J, K, L) with several matrilines within each pod. As of July 2021 there are only 74 individuals. The world's oldest known killer whale, Granny or J2, had belonged to and led the J pod of the SRKW population. As of October 2016, she is missing and presumed deceased. J2 was estimated to have been born around 1911, which means she would have been 105 years old at the time of her death, and the oldest known orca to date. On July 24, 2018 the first calf born in three years died after being alive for only half an hour.
