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.
However, as Barbara and other scientists have documented, animals exhibit behaviors that align with grief in humans — altered routines, withdrawal, loss of appetite, and visible mourning rituals.
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. The southern resident orcas form a closed society with no emigration or dispersal of individuals, and no gene flow with other orca populations. [1]
Female orcas can live up to 90 years, and male orcas live up to 60 years. Whales can communicate through sounds ranging from clicks, whistles and pulsed calls. These loveable creatures are highly ...
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 ...
The orcas’ dorsal fins are bent in opposite directions — the inspiration for their names. The two travel huge distances along South Africa’s eastern coastline up as far as Namibia.
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.
