Whales Move Essay

Whales in captivity suffer through a great amount of emotional abuse . In captivity, Children can be separated from their mothers, and whales that are taken from the wild are separated from their families ,which can consist of up to 40 members (National Geographic). Whales are very family oriented and each pod of whales has their own dialect when communicating. Whales are social creatures and by depriving them of social activity and their families, they become depressed and

The study was first embarked in an attempt to assess what could be done to help the depleting population of the wester Pacific whale. However, it later turned up evidence that may imply that western Pacific whales may just be California gray whales with different swimming patterns.

As mammals, they also give birth to a live animal, called a whale calf. Unlike humans, who can take around one year to learn how to walk, whale calves are born already able to swim.

They can swim up to 100 miles per day playing and hunting, while they cannot do anything of the sort in a tank. (“Whales and Dolphins in Captivity”) Entire pods of Orca Whales, up to 40 individuals, can be hunted at a time. Only the young and fit are taken, and during the process, many creatures are injured or killed. Overall, the wild capture of whales is brutal and unsafe for, not only Orca Whales, but sea life itself. (“Whales and Dolphins in Captivity”) When captured, they are put into holding tanks, often smaller than show pools.

Orcas are complex social creatures deserving freedom and respect, not captivity in theme parks under the guise of public education and entertainment. Aquarium staffs say captive whales are priceless educational tools. However, people can educate their children by bringing them to the wild instead of bringing the wild to them at the expense of the Orcas health and well-being. "The price of a family admission ticket is what continues to drive this cruel spectacle," according to Michael O' Sullivan, the Executive Director of The Humane Society of Canada (Whales in Captivity, 2010, Para. 3). Orcas suffer in many ways in

Everyone loves going to marine parks such as SeaWorld and Marineland. They offer many spectacular shows with dolphins, sea lions and birds. However, the main attractions they offer are orcas, or as they are better known as killer whales. Highly intelligent and with acute senses of sight and hearing, they are apex predators. Recently, the possession of orcas has been a big topic of controversy. Many people believe that the animals are being mistreated in captivity. Their captivity limits their freedom and enjoyment. Many orcas suffer from poor physical and mental effects in captivity. Killer whales will usually travel between 50 and 100 miles per day in the wild, but in captivity all they can do is swim in circles or float for no reason. In the wild, killer whales live in pods of

The ancestors of the whales transitioned from being land bearing animals to becoming animals that live in the ocean. While the original ancestor of whales lived on land as it evolved it was able to start to enter the water until it struggled more to get on land than to get in water until the whale’s ancestors began to live exclusively underwater.

The earliest whales were land animals with long skulls and carnivorous teeth. Analysis of whale skulls showed major morphological changes, including changes to the skull size, shape, teeth, and nostrils. Fossil evidence shows that the trait of interest, the nostrils, can be found on fossils of the earliest whales, dating back to about 50 million years ago. Evolution occurred multiple times since then, each time resulting in the nostrils migrating further back on the skull. Eventually, the pair of nostrils positioned itself right on top of the head. These nostrils are the blowholes we see positioned on top of modern whales today. In addition, another momentous change in the nostrils occur when order Cetacea splits into Mysticetes and Odontocetes. Suborder Mysticetes

Why didn’t they just stay on the land like just about every other mammal in the world. Whale’s ancestor the Indohyus resembled that of a wolf or even deer. Over time, it started swimming in the water more, hunting for food in the water more, and traveled in the water more. Through the process of natural selection, the phenotype of the Indohyus slowly changed over time to accommodate for these changes. It accommodated the changes by slowly forming aquatic features that allowed it to move faster and more efficiently in the water, as well as hunt better in the water. The whale is one of the few carnivorous sea creatures, and it is believed to be so because of it’s early ancestors hunting on land live other mammals such as wolves. This would explain the strange diet of whales compared to other sea creatures like fish and algae. Being one of the largest animals in the entire ocean, whales could easily devour any meal they wanted, though more recently, the diet of the whale has minimized to smaller animals like krill but in large quantities. Along with its outward appearance, its behavior has changed dramatically. Unlike its ancestors who hunt on land or close to land, whales hunt deep into the sea a very low depths, since they are capable of doing so with their fully developed lungs, another trait that suggests evidence towards it having land mammal

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.

Whales resort to pacing around the tank in circles to emulate the fast strong feeling of a swim normally done in the wild in an attempt to keep their dorsal fin upright.

Whales were peeled by vessels, conserved by the cold, and packed in barrels. 1719 Greenland whaling operation spread into Davis Strait. Davis Strait whaling operation was in the power of the Dutch and German until 1780. The Britain had to leave and service their industrial revolution. From the beginning of the 1690s the British had hunted down whales (have been fishing) in the Bay of North America colonies,also in Rhode Island, Long Island, Cape Cod. These were new centers of activity for (whaling) fishing. Then, during 1712 the Nantucket vessel capture the first sperm whale,these became a brand new center.

In captivity they have very little space and cannot behave naturally. A concrete tank can never replace their ocean home. Killer whales are usually around 20 ft-30 ft long, basically the length of a school bus. They travel 100 miles a day in the wild. In captivity, they swim along the same walls about 1,400 times a day. Putting whales in a size of a bathtub is not the best idea for their health and entertainment.

Whales are large aquatic mammals. Like every other animal they did not start off like that. Whales came to be after millions of years of evolution. Every aspect of the current whale was decided by nature. The blowhole, dorsal fins, lack of teeth and tail fluke all came from years of other creatures such as the Mesonychids and many other animals.

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.
