The Killer Whale, that has a ring to it doesn’t it? Orcas, Killer Whales, are not actually Whales, in fact, they are a part of the Dolphin family. The name “Killer Whale” developed over time stemming from “Whale Killer.” They were once called Whale Killer due to the fact that sailors witnessed their attacks on larger cetaceans. Orcas are the largest member of the Dolphin family and the largest orca ever captured was 32 feet long. To put that in perspective, that’s about the size of almost 7 humans put together! Because of their size and strength, they are the largest apex predators on Earth. Although whaling was hugely popular, there is only one known community of Orcas, that are in fact, endangered having only 82 members of its pod. This community of orcas is called the Southern Resident Community. There …show more content…
They thrive on social interaction and being a part of a community or pod. Typically, Resident pods will have a stable population with its members appear to have never left or joined another population except for death and birth. Transients tend to have two sized pods, large or small. Based on studies, the bond between the Resident pods is called a matriline. What this means is that this pod have a strong bond with one another and the population consists of connected maternal descendants. A matriline can have one generation but range up to four or five generations in its pod. The pod size can range between each community; the sizes range from about 7 members to about 100. The eastern North Pacific Ocean pods have a size of about 100 members while Transient pods only have a pod size of about 7, usually consisting of all males. Resident pods usually have a pod size ranging from 5 to 50 members. Alaskan and Antarctican pods have been documented to range from 100 to 2,500 members. It was noted that the migration of prey played a part in the pod sizes. It is also said that mating and social interactions could cause these larger
Orca whales are the largest members of the dolphin family. Orcas are very curious creatures, they like to sky hop, which is when they poke their heads out of the water and look around, and they can also dive to as much as a hundred feet. These social animals live in pods and stay with them for their whole lives. They are so family oriented that they can may sleep together in a tight circle and have synchronized breathing. Orcas can grow up to thirty-two feet and can weigh nine tons. They typically eat five percent of their body weight and are amazing hunters. The lifespan of an orca in their natural habitat is about fifty years. This lifestyle for them is wonderful because they can swim as far as they want to and are free. Orcas should not be held captive because the capture process is dangerous, it is not good for their health, and their trainers are at risk. Free Willy. Dir Simon Wincer. 1993.Video.

Blackfish: The Documentary Entertainment is a word that invokes feelings of fun and pleasure. It is an exciting time with family and friends filled with joy and laughter, especially at amusement parks. However, what about the whales entrapped at water parks? How do they feel about this? Are they content with their environment?

“… building a tank the size of Rhode Island wouldn’t be large enough for a six-ton male killer whale such as Tilikum, an animal capable of swimming 100 miles a day,” states an anonymous whale expert. Whales have been in captivity since 1861 when P.T. Barnum displayed the first live whale that was captured in Canada. However, Barnum had no idea how to care for the mammal and it died after only a week in captivity. (Animal Legal and Historical Center, 2014) Being up close with killer whales could give us some clues about how they interact with each other, including physical behavior, their dialect, and how their pods work together as a family unit. However, what we are finding is that whales who belong in the wild are suffering in captivity. Killer whales have no record of ever harming a human being in the wild. In captivity, there have been many incidents of killer whales harming or even killing their trainers. What would cause them to do this in captivity, but not in the wild? They have been known to resort to aggression toward themselves and each other, in what scientist believe to be a stress induced behavior. (Animal Legal and Historical Center, 2014) Evidence against having these wild animals in captivity is increasing and we need reevaluate the value of capturing and holding killer whales for our educational purposes, enjoyment, and profit.
Orcinus orca is the scientific name for the massive marine mammal. Orcas are not rare, but have declining numbers in some areas (Martin.) Orcas are found from the Artic Ocean to the Antartic Ocean. (Britannica) They belong to the Delphinidae, or dolphin family, which is the largest of their species. Female orcas grow to be at the most 15 feet, and weigh up to 4 tons, but the males can grow as large as 20-30 feet, and weight up to 8 tons. (Martin) The color of the orca is white in some spots, black on the majority of the body, and gray just behind the dorsal fin. It is white on the chin, belly and the eye. The white patch above the eye is usually mistaken for the eye, and may confuse their prey, but acts as a camouflage for the eye. The name “killer whale” makes people tend to believe that this is a viscious man-eating mammal, yet it is one of the most shrewd, docile and playful species of the marine mammals. The orca is sexually mature at 10-15 years of age, much like humans, which is 12-13 years of age. They tend to mate year round, and is able to have a calf every two years. It is interesting to know that lactation of the mother lasts 12 or more months (Wynne.) The life expectancy of orcas is 45-50 years of age.
To fight is to stand up for what is right, break through the walls of what is acceptable, and to have the fire blazing in the eyes of a warrior. Throughout life society has taught humanity to form into a definite way that should not ever change, but through life there has been a small population who are immune from societies spell. The outcasts that must battle to stand up for what they believe is right. In the novels Antigone, Anthem, and in the movie Whale Rider, the main characters fight for what they believe is right by standing up to society's norms the society has deemed acceptable.
Orcas, or killer whales are majestic giants of the sea. They are actually the largest type of dolphin. They have long black bodies with distinct white patches near their eyes. A killer whale can be up to 32 feet or more in length, and weigh up to 12,000 pounds. Females are a bit smaller, but live longer (Gorman). The name “killer whale” apparently came not because it is a vicious whale, but because it preys on whales. They do not have any natural predators, and they are considered the “top dog” of the ocean. Not even the great white shark stands a chance against these superb killers. “Unlike sharks, killer whales are cautious hunters, sometimes spending hours harassing a 1,000-pound sea lion so it can easily be drowned” (Francis). Orcas use many hunting tactics that are unique to their species, which is what makes them invincible.

Family therapy is often needed when families go through transitions such as separations between parents and divorce. According to research, “the power of family therapy derives from bringing parents and children together to transform their interactions” (Nichols, & Davis, p.18), as problems need to be addressed at their source. The children who are the most vulnerable, when parents decide to separate, exhibit symptoms which are exaggerations of their parent’s problems (Nichols, & Davis, p.18). Frank and Walt Berkman are the examples of how children cope and adapt to the stressors of family separations such as marital separations and
Orcas, commonly known as killer whales, are actually the largest member of the dolphin family. They were given the name “killer whale” by sailors who often observed them attacking and killing seals, sea lions, walruses, penguins, dolphins, polar bears and even other whales (Orcas).
A hero is someone who will attempt everything in their power to help others and risk everything they have to help others. In the movie, The Whale Rider, you can clearly see all the elements of The Hero’s Journey. A young girl named Paula Apirana, is living in a small village with her grandparents. Paika’s dad, who is living in Spain, returns to see Paula and proposes that she should come live with him. She declines the offer and decided to stay with her grandparents. Paula then secretly tries to learn the important ritual, that only males are allowed to learn. Her grandpa, Paka, gets extremely angry at her until he realizes that she is the “chosen one” to perform the ritual. Paika goes through many difficult challenges, however she manages
The book In the Heart of the Sea: The Tragedy of the Whaleship Essex by Nathaniel Philbrick, is an inspiring story about an Essex from Nantucket, getting attacked by a eighty-five ton sperm whale miles deep out in the ocean. In these times, going on any ocean expedition had its precautions. While much focus on food, drinking water, medication and a method to cure illness, the most overlooked impairment was the creatures of the ocean. While the men of this vessel left the docks as predators, the survivors of the ninety- three-day journey on three small harpoon boats came back as prey. This story gives a great depiction of the potential of the sperm whale as well as the devastation that they can bring.
The Humpback Whale, Megaptera novaeangliae, is part of the marine mammals group. They are found in oceans all over the world, they live in open waters. Even though they are mammals, they do not live on land (Monterey Bay Aquarium). Humpback whales are known for their magical song that can travel great distances. These gentle giants are omnivores, their main diet is krill. They are mostly found near coastlines feeding on tiny shrimp-like krill, plankton and small fish. Humpbacks migrate annually from summer feeding grounds near the poles to warmer winter breeding water closer to the Equator. Humpback whales are powerful swimmers, and they use their massive tail fin, called a fluke to propel themselves through or even out of the water! Mothers and their young swim close together, often touching one another with their flippers with what appears to be gestures of affection. Even though it takes more than one year for a humpback whale to grow fully, mother whales leave them after one year (National Geographic).
Whales are perhaps by far the most mysterious creatures of the deep blue. It is not that we do not know much about the whales; rather, it is the reasons behind the ways that they act and communicate that we do not yet understand. Their ways of life have been researched in the past and present. Many speculations have been made as to why they do what they do, but the speculations themselves have speculations. Everyone has their own opinion but an opinion is not enough to unravel the mysteries behind a personality.
What is the largest fish in the world? The answer would be the Rhincodon typus, or commonly known as, the whale shark. The whale shark is vey unique because unlike normal sharks, the whale shark is a filter feeder and so, does not have use of its teeth. The whale shark is also about the size of a bus. However, like many animals in the world today, they are considered vulnerable according to the IUCN. They are seen often in the tropical areas, but many behavior and movement mechanism of the whale shark are still unknown.
