The International Union for Conservation of Nature assesses the orca's conservation status as data deficient because of the likelihood that two or more orca types are separate species. Some local populations are considered threatened or endangered due to prey depletion, habitat loss , pollution (by PCBs ), capture for marine mammal parks , and ...
Although the orca is not an endangered species, some populations are threatened or endangered due to bioaccumulation of persistent organic pollutants, depletion of prey populations, captures for marine mammal parks, conflicts with fishing activities, acoustic pollution, shipping vessels, stress from whale-watching boats, and habitat loss.

A pod of orcas moving through the inland waters of Alaska. The Orca Welfare and Safety Act is a bill passed in the U.S. state of California in 2016. The bill phases out the holding of killer whales in captivity and establishes standards for treatment of all remaining captive orcas in zoos.
Killer whales play an important role in our ocean's ecosystem. Female orcas can live up to 90 years, and male orcas live up to 60 years. Whales can communicate through sounds ranging from clicks ...
The U.S. National Marine Fisheries Service listed this distinct population segment of orcas as endangered, effective from 2005, under the Endangered Species Act. [2] In Canada the SRKW are listed as endangered on Species at Risk Act Schedule 1. [3] They are commonly referred to as "fish-eating orcas", "southern residents", or the "SRKW population".
Simmons worked as Tilikum's team leader during the orca's first few years at SeaWorld Orlando and claims the documentary "has done immense harm to species preservation" by spreading disinformation.
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms.
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.
