As social animals, orcas rely on a system of communication tools to talk with members of their pods, navigate the ocean, and hunt. This isn’t legend; it’s reality. They are the only species in their specific genus, but are most closely related to dolphins from Australia and South East Asia. Two humpback whales were already on the scene as the killer whales, or orcas, attacked the grays. Fishermen and killer whale “collectors” believed there were thousands, perhaps tens of thousands, of wild whales roaming the Pacific coast. Killer whales, or orcas, are the largest species of dolphin. They don’t just “see” objects; it’s possible they can echolocate what’s inside of them. A pod of killer whales, which included amongst its members a distinctive male called Old Tom, would assist whalers in hunting baleen whales. The orcas who earned killer whales their reputations as monsters were the transients, which scientists now refer to as Bigg’s whales. Killer whales can see about as well as humans. Killer whales may be kept in human care, but they are not domesticated in any way. Mothers carry their babies in utero for a 17-month gestation period, and they give birth every three to 10 years until becoming menopausal around age 40. Killer whales know how to work with humans—and save them—but humans have rarely been inclined to help the killers. But orcas use echolocation to lock in on their prey. In fact, the social status of a killer whale could be a matter of life and … But Tom continued to herd larger whales for his taste of tongue. The humans shot them. Studies of dead residents have revealed that their diets are so specialized that when they’re living in the wild, they will almost never deviate from it, even if the alternative is starvation. The white belly can camouflage into light streaming from the sky toward the sea, which also makes the orca difficult to pick out from beneath. Proposals from government officials included arming the coast guard with explosive bullets, bazookas, dynamite, depth charges, and mortars. But in 1964, the belief was that there were too many killer whales, they were ferocious, and, at best, they were a pest that should be eradicated. Orcas have never bitten a human in the wild and seem to have no interest in learning what human meat tastes like. Another possible explanation is that, unlike our species, orcas would never harm another creature they consider intelligent. Not only do residents and transients have different feeding and hunting habits, but they also have different languages, rules, and rituals. On the west coast of North America there are two groups of residents—the northerns, who roam between southeast Alaska and southern. In 1973, he and Ian MacAskie—his colleague from Canada’s Pacific Biological Station in Nanaimo—were studying whales in the Johnstone Strait when they realized they could tell the individuals apart by the nicks, scratches, and marks on their dorsal fins and the shape of each whale’s “saddle patch”—a unique pattern located behind the dorsal fin. There are a few theories about why orcas don’t attack humans in the wild, but they generally come down to the idea that orcas are fussy eaters and only tend to sample what their mothers teach them is safe. Ever since Burich and Bauer and the other men in their original hunting party arrived with their weapons, the whales have steered clear of their usual fishing grounds—a route they’ve probably been following for thousands of years. At the start of spring 2016, after a year that saw the biggest baby boom since the 1970s, there were only eighty-three southern residents in the Salish Sea. The Australians of Eden had worked with the orcas for almost a hundred years. Mark is a journalist, filmmaker, and author of numerous books, including, How the Killer Whale Avoids Eating People, Helped 19th-Century Whalers, and Became Public Enemy Number One, AMA with Dr. Russ Mittermeier from “Primates”. At the top of the food chain, whales have an important role in the overall health of the ocean. Some longtime whale watchers are convinced that orcas will perform when they have the chance to endear themselves to humans who are working to save them. Orcas will work together to support and transport their injured mates for weeks at the risk of their own health. The two larger whales consider their injured pod-mate. Only 549 whales were spotted by volunteer scouts between California and Alaska. Humans and killer whales have so much in common that the latter are now serving as a model for our species by showing how ecology, culture and evolution reveal themselves in genomes.. Orcas and humans … In North America and Australia, there are stories of orcas herding fish—and even other whales—to make it easier for fishermen to catch them. Killer whales can survive in the cold polar regions of Antarctica and the Arctic Circle, as well as the warm waters of the equatorial regions. Fishermen blamed the killer whales, which were swimming beyond their usual hunting grounds in search of sustenance. Despite seeming like identical creatures with their notable black and white bodies, each individual orca is unique and identifiable by its dorsal fin and the saddle patch. Saddle patches are light-colored areas located behind the dorsal fin, and they can be open or closed, often white or grey, and each orca's saddle patch has a distinct shape, making it possible to tell the difference between individuals.
