Ellis. Another conservation concern was made public in September 2008 when the Canadian government decided it was not necessary to enforce further protections (including the Species at Risk Act in place to protect endangered animals along their habitats) for killer whales aside from the laws already in place. [114], Killer whales are sophisticated and effective predators of marine mammals. [161], The complex and stable vocal and behavioural cultures of sympatric groups of killer whales (Orcinus orca) appear to have no parallel outside humans and represent an independent evolution of cultural faculties. [86], In the Antarctic, killer whales range up to the edge of the pack ice and are believed to venture into the denser pack ice, finding open leads much like beluga whales in the Arctic. And in the ambush sits one male, and the other members of the group are waiting at a distance. [217] Keiko however did not adapt to the harsh climate of the Arctic Ocean, and died a year into his release after contracting pneumonia, at the age of 27. Some local populations are considered threatened or endangered due to prey depletion, habitat loss, pollution (by PCBs), capture for marine mammal parks, and conflicts with human fisheries. [208][209], Competition with fishermen also led to killer whales being regarded as pests. [14], They are sometimes referred to as "blackfish", a name also used for other whale species. Calves are born with a yellowish or orange tint, which fades to white. [193] The Tlingit of southeastern Alaska regarded the killer whale as custodian of the sea and a benefactor of humans. They possess canine teeth like a grizzly bear’s, and are known to hunt porpoises, dolphins, sea lions, and seals, according to the radio station. [125] Killer whale cannibalism has also been reported based on analysis of stomach contents, but this is likely to be the result of scavenging remains dumped by whalers. Gestation varies from 15 to 18 months. The boat’s first mate Stephanie Hayes, a graduate student in marine biology at the University of Alaska Fairbanks, was able to snap some incredible photos of the orca. Some males become "rovers" and do not form long-term associations, occasionally joining groups that contain reproductive females. [206] The sled dogs' barking is speculated to have sounded enough like seal calls to trigger the killer whale's hunting curiosity. Males typically range from 6 to 8 metres (20 to 26 ft) long and weigh in excess of 6 tonnes (5.9 long tons; 6.6 short tons). [153], Killer whales have the second-heaviest brains among marine mammals[154] (after sperm whales, which have the largest brain of any animal). Tl’uk was determined to be a 2-year-old Bigg’s killer whale. [164][165] The lifespans of wild females average 50 to 80 years. They have been known to attack baleen whale calves, and even adult whales. They called orcas asesina ballenas, or ‘whale They were so thrilled when they figured out what was going on, that we were playing games. [193] For the Kwakwaka'wakw, the killer whale was regarded as the ruler of the undersea world, with sea lions for slaves and dolphins for warriors. [59] Its integument, unlike that of most other dolphin species, is characterized by a well-developed dermal layer with a dense network of fascicles of collagen fibres. Humans could be a major cause of death for killer whales, new research says. They were often called "whale killer," which eventually became "killer whale." Bigg’s killer whales are predatory orcas among a variety of different orca species.
