Some local populations are threatened or endangered due to prey depletion, habitat loss, pollution (by PCBs), captures for marine parks, and conflicts with fisheries. In late 2005, the southern resident orcas were added on the U.S. Endangered Species list. Orcas rarely pose a threat to humans, and no fatal attack has been recorded in the wild.
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 ...
In the case of orcas like Tahlequah, this includes addressing environmental issues such as water pollution, damming rivers, and overfishing. And she might be the best encouragement for advocacy yet.
Orcas are large, powerful aquatic apex predators. There have been incidents where orcas were perceived to attack humans in the wild, but such attacks are less common than those by captive orcas. [1] In captivity, there have been several non-fatal and four fatal attacks on humans since the 1970s. [2]
The earliest recorded post-colonization interactions between Salish Sea orcas and humans occurred in the early 1960s, when fishermen in Seymour Narrows, near Campbell River, BC, began to complain of orcas taking salmon from nets and interfering with fishing operations. At the time, orcas were not only viewed as costly competition with fishermen ...
Orkid at SeaWorld San Diego. Dozens of orcas (killer whales) are held in captivity for breeding or performance purposes. The practice of capturing and displaying orcas in exhibitions began in the 1960s, and they soon became popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness, and sheer size.
L98 or Luna (c. 19 September 1999 – 10 March 2006) also known as Tsux'iit, was an orca born in Puget Sound.After being separated from his mother, Splash (1985–2008) while still young, Luna spent five years in Nootka Sound, an ocean inlet of western Vancouver Island, where he had extensive human contact and became recognized internationally.
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.
