SOUTHERN RESIDENT KILLER WHALE

An English naturalist Charles Darwin (1802-1882) developed a theory of biological evolution. He studied variation in plants and animals during his five years’ voyage around the world in the 19th century. Darwin studied hundreds of species, which he researches variations between locations. His theory states that all species of organism arise and develop through natural selection. Natural selection is the process of organisms that adapt to their surrounding environment, which tend to survive and produce more offspring. Killer whales are remarked to have evolutionary links from land dwelling organisms, millions of years ago. This paper will display the evolution and natural selection of the killer whale.

    One of the things this company claims is that the killer whales actually live longer in their care. According to the website Sea World of Hurt, this is completely false, killer whales in the wild have a similar life span to humans, they can live from anywhere to 50-100 years. Held captive, these animals hardly live past twenty-five years. In the wild, an orcas dorsal fin is straight, which is the way it should be. In captivity, you will mostly see their dorsal fins flopped over or completely collapsed.

However, the change from ancient whales to modern whales is drastic.

    Whales living in captivity become aggravated and have been known to take out anger on themselves by self harming. In the pools they live in, metal bars are placed in between the pools to prevent the killer whales from swimming to another pool. On several occurrences, the whales have attempted to bite and break the metal bars. This leaves the whales with broken teeth and a risk of infection. Infections in killer whales can lead to death in many cases. If a whale gets an infection, they have to be taken out of the pool and placed into another pool by themselves to prevent any problems with other killer whales they live with. In many cases, whales with infections need serious care from whale specialists.

    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.

    In Chinese tradition, Shark fin soup is called as “a celebration soup”, which people eat it to celebrate in various occasions. Moreover, people also believed that shark fin consisted of diverse nutrition values which provide them virility, wealth, and power(Wolchover, 2011). These beliefs lead to the beginning of poaching for sharks, the top of food chain in the sea world. Surprisingly, although people are aware of the decreasing number of sharks since the old days, around hundred million of sharks are still hunted each year(Heltus, 2013), to be served on luxury tables surrounded by those believers in things that they do not even prove whether the belief is reliable. Therefore, in the generation that people are mostly educated, sharks should no longer have to be continuously killed for their fins.

  • Killer Whales in Captivity

    After watching several documentaries on how poorly killer whales are treated in captivity, it drew me into researching more information on the treatment of Killer whales that are kept in captivity. I found several scientific journals, and articles on wild life facts of killer whales and I found published books on the treatment of killer whales in captivity. The information I found includes both wild killer whales and killer whales kept in captivity. With the information I found, I plan to prove the shortened lifespan and health problems killer whales get while living in captivity are not normal. In fact the information you learned about killer whales from aquariums and commercial parks are false. This paper will argue why killer whales should not be held captive in commercial parks. This Paper will include information on the killer whale’s diet, the killer whale’s communication, and the killer whale’s physical traits.

    Orcas, also known as killer whales, are amazingly intelligent and are a top predator, much like humans. However, when the top predator of the ocean collides with the top predator of land, the situation can become fatal for both humans and the whales. Holding these incredibly massive marine animals in captivity is not only inhumane and detrimental to the whale’s health, but also a potentially fatal activity for humans to participate in.

    Orca whales do not like to be taken from their family, held captive for many decades and put with other whales that they do not know. No other living organism on this planet would like to be put through the same thing. Orca whales are highly social animals, they are very intelligent, and are very emotional. If they are kept away from other whales, fed intermittently and received little attention from staff makes them get very emotional and can lead to death of people and the whales. Orca whales should not be held captive; they are beautiful creatures that are not great for people’s amusement and if they are treated poorly, they will act poorly.

    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.
