The killer whales are mammals. They have two common names the killer whale and the ocra. Killer whales inhabit most of the world’s oceans, going from warm waters to freezing cold waters (Monterey Aquarium). Not all of the killer whales are known because their are so many. Orca’s are very social and travel in pods. The whales usually stay with the same pods of whales as they travel. Ocras usually migrate with their food, and they also have seasonal migrations. (Sea World). The food they eat is fish, sea lions, squids, penguins,sea turtles, sea birds, seals, baleen whales, other toothed whales {dolphins}, walruses, sea otters, sharks, the can also eat humans, polar bears, reptiles, mooses, and other killer whales [that are dead](Sea World)(National Geographic). They are carnivores (National Geographic). Killer whales do not chew their food they swallow their whole or rip off chunks. Ocras hunt in pods and to confuse their prey they herd them to the top of surface then attack. They can also jump on land to get their food. Killer whales have cone like-shaped teeth that are thre...
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.

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
Imagine yourself living in a bathtub for 25 years and you could do absolutely nothing about it. Wild orcas, better known as killer whales, have been captured to entertain audiences worldwide at aquariums. The most popular location is Sea World. Growing up in Miami, I could not control my excitement when it came time to go visit Lolita, the killer whale at the Miami Seaquarium. To be able to see such an amazing creature right in front of me was mind blowing.
For 50 years SeaWorld has entertained park guests with numerous stunts involving the majestic sea creature, the orca, also referred to as the killer whale, and their human trainers. What the on-lookers don’t see at these shows is what goes on behind the scenes: how the whales got there in the first place, and the conditions in which they are housed.
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
Image sitting on the beach one July morning. The sun is beaming down and decide to go for a swim. As you approach the water, you see a whale unusually close. You begin to get nervous as it continues to approach the shore. However, you aren’t worried because you know that they are confined to the sea. As the whale comes near you can see it clearly. Just as you think that it will turn around, the whale walks out of the ocean!
Killer whales are one of the most fascinating displays of ocean life. The killer whale has characteristics that are important to its survival in the ocean. It is interesting to know that killer whales have a plentiful diet. It is astounding to see how killer whales behave in the ocean. I plan to tell you about the killer whale, its characteristics, its diet, and its behavior in the ocean as well as the predation of the orca.
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).
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.
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.
Many people can feel connected to the earth and their surroundings by observing and learning the way of the animals, including the whales. The Bowhead whale has been an important part in the Inuit-Inupiaq people of northern Alaska’s way of living. Native Americans have used animals like the whale in their stories to explain life and moral values. An American Indian author, Vine Deloria Jr., stated that, “Native Americans saw themselves as being related in some fundamental manner to every other living species. They believed each species had a particular knowledge of the universe and specific skills for living in it.” (Caduto and Bruchax, XI) Vine Deloria along with many other Native American authors has taught us through their words the roles that animals play in the Native American culture. The animals in these stories teach us some of the same values that are displayed in traditional literature, including fairy tales, nursery rhymes and The Bible. We can see how Bowhead whales’ physical traits and connection to the earth are linked to Native American culture by examining scientific information and Native American literature.
The origin of modern day whales, a mystery that has puzzled paleontologists for years, may have just been solved with the discovery of an ankle bone. This discovery might sound simple and unimportant, but the bones of these ancient animals hold many unanswered questions and provide solid proof of origin and behavior. The relationship between whales and other animals has proven to be difficult because whales are warm-blooded, like humans, yet they live in the sea. The fact that they are warm-blooded suggests that they are related to some type of land animal. However, the questions of exactly which animal, and how whales evolved from land to water, have remained unanswered until now.
Whales are considered to be intelligent mammals, but they live in the water despite the fact that mammals evolved on land. Paleontologist Phil Gingerich has been studying the evolution of whales since 1978. In 1978, he and his team discovered a rock in Pakistan with a skull on the inside. The skull appeared to be a wolf-like animal upon first sight, but Gingerich noticed the distinct whale ear on the skull. The skull, which had characteristics of both whales and other mammals, was that of a common ancestor of the whale known as Pakicetus. Many scientists believe that Pakicetus resembled the seal in its appearance. Pakicetus could not be considered a whale, since its backbone and limbs do not have similar features to those of a whale. Therefore, it is considered an ancestor of the whale, since it has some features of the whale and some unique features (or features of other mammals). Today’s whales have mammalian characteristics, which prove that they have evolved from a common ancestor of the mammal. A whale’s fin also has traits that are common of many species. The fin seems to be similar to that of a fish, but the bones on the inside of the fin are similar to those on a bird’s wing, a monkey’s arm, and a frog’s limb. This seems to be proof that these organisms, and many others, all evolved from a common ancestor. Other proof that whales have evolved over time lies in Egypt in the Valley of Whales, where over 400 fossils of whales currently lie. The desert used to be a large sea that was home to a few kinds of whales. In the Valley of Whales, Gingerich discovered the Basilosaurus, which had small hind legs, toes, and a mobile knee and lived 35-41 million years ago. This fossil is considered to be a transitional fossil, since it ha...
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).
