Sea Lion Research Paper

Improved Essays
As many of you have noticed nature happens on its own, the Sea Lions have not been treated well lately, they have been getting blamed for something that is not their fault! Due to climate changes the sea lions have been eating so many salmon because of how they reacted to the weather changes, how the weather has increased its temperature so highly. A fact that I once read and legally changed my mind said “Killing sea lions will not change the future for the salmon, it will simply distract attention from the fact that the greatest challenges to salmon recovery are not being addressed”. In most articles that I have read there are mostly negative facts towards the sea lion’s.

Yet sea lions continue to be blamed for eating “too much” of their natural prey, and some say they must be killed to save the fish. 2007’s estimate of 4.7% of the fish to barely 1% of the run in 2012.Sea lions have been treated unfairly, they should get the chance to live freely.
Throughout the 19th and early 20th centuries, sea lions were Slaughtered for their hides, oil rich blubber and even their genitals which the chinese pharmacists turned into a tincture, and intended to rejuvenate the aged, by 1927 fewer than 1,000 remained. This shows that back then and still going on today they have been mistreated and threatened. But a few decades after plummeting fur prices, that put hunters out of business but truly until 1972, 45 years after what the chinese pharmacists did. Imagine what else they could have been doing during those 45

Sea lions are mammals, like us, they encounter similar diseases and problems such as pneumonia, bacterial infections like leptospirosis, which affects their livers and kidneys, And cancer caused by pollution such as DDT and heavy metals in the environment. Other challenges include malnutrition due to maternal separation or lack of prey due to the effects of “El Nino” or other climatic changes and environmental factors. The most visible consequence has been the baby Sea Lions, which have show up stranded on beaches from Mexico to San Francisco for the past three years. But some in the marine science community are asking whether putting such animals back into the ecosystem is the right thing to do. Where are those sea lions going to go?, says Josiah Clark, a consulting ecologist in San Francisco who has studied birds and marine life for more than 20

Collard has studied the sea otters’ life course in Alaska since colonization. She studies topics such as the near extinction of sea otters during the fur trade and the Exxon Valdez oil spill that resulted in the death of thousands of sea otters.…

    California Sea Lions (Zalophus californianus) are one of the rehabilitated animals in Southern California. The brain lesions in So Coal Pinnipeds are among several reported causes of their morbidity and mortality within the last few decades. They generally range from traumatic, to inflammatory ( encephalitis) and degenerative brain lesions (encephalopathies).

    This has led to sever over population of seals from having a lack of predators and therefore a large decrease in their food source, the threatened species Atlantic cod. If unchecked the seals will continue to deplete the cod stocks causing them to run out of a sufficient food source causing the seals to die of starvation. This can lead to the marine ecosystem in this area to collapse. There is a common misconception that the seal hunt is inhumane because of some of the tools tradionally used in the hunt. In fact, the way that the seals are killed is actually very humane.…

    An article counteracting the renowned film, Blackfish, a documentary about the inhumane treatment and situation of orcas in captivity, was released by Seaworld Cares. Seaworld Cares is a foundation for animals supported by Seaworld. The article was the company’s retort against the film’s “ultimately false and misleading points”. The main purpose of the article is to persuade the reader, while providing some information to support their points. They wish to urge the reader to believe that not everything in the film, Blackfish, was true nor trustworthy.…

    Why Orcas Should Not Be Kept in Captivity For many years killer whales have been brutally used in the entertainment industry. These mammals are not only being used for public display, but are being treated unfairly. Instead of being left alone in the wild as they should be, they are being taken away not only from their homes but from their family. Many people may not know this, but behind closed doors at the various Seaworld's, located all over the country, these creatures are being held and “cared for” in unsafe barbarous water tanks.…

    1) After looking at the graphs in Figures 3 and 4, it is obvious that killer whales are the cause behind the deaths of a large amount of sea otters. Despite the data for Figure 3 showing all sea otter the researchers encountered, while the data for Figure 4 showing sea otters with radio tags, both figures still show a drastic decrease in sea otter population with the only main difference between Kulak Bay and Clam Lagoon being the ease of access that killer whales have to the areas. The researchers looked at 2 different sets of data because they wanted to show the general decline in the population in figure 3 and then show a more specific set of otters to show that the general decline was not because of human error. By having figure 4 focus on…

    The Missing Sea Otters

    • 325 Words

    According to the article “Search for the Missing Sea Otters: An Ecological Detective Story” by Mary E. Allen and Mark L. Kuhlmann, the sea otter population has been decreasing at a rapid pace since the 1990’s in Aleutian, Alaska. This is demonstrated by article “What Could be the Cause of Decreasing Otter Numbers” which states that in 1997, the decline of the sea otter population had increased to about 90%. They hypothesize that the decrease in the sea otter population has been caused by their predator, the killer whale because the sea otter’s bodies do not come ashore. The evidence suggests that killer whales are eating the sea otters because in the text “What Predator Could be Causing the Large Decrease in Otter Numbers”…

    I chose this topic for my poster as not only is it a current social injustice problem, but also a serious one. I feel the need to stand up for the animals of SeaWorld, as they have no voice of their own. All animals that can not live without humanity should be able to live as normal as possible. For example, the animals at SeaWorld could live at open-sea sanctuaries, if they can not be returned to the wild.…

    Killer Whales are a very large and strong breed of marine mammals that belong to the dolphin family that can grow up to ten meters long and can weigh up to six tons. Theses whales are a highly social species that are very intelligent with an excellent sense of hearing and have developed highly complex communication systems. Killer whales are immediately recognizable by their distinctive black-and-white coloring, when you see these magnificent creatures many people immediately get the idea of Shamu from SeaWorld and the tricks they preform, most people don’t remember that that captivity is limiting the whale’s freedom and life. Captivity is not only taking away and damaging these animals mental and physical health, it is also playing a role in taking the lives of the trainers that risk their lives swimming with killer whales just to make a profit for SeaWorld.…

    Even after the ban on capturing orca whales in British Columbia enacted, SeaWorld pushed to find more places to capture the orca whales for the parks entertainment. “Confined and desperate, the orcas futilely searched for a way out. Their frantic cries reverberated over the cove and were heard for miles. The squeals, clicks and shrills were so disturbing and deafening that Dr. Newby says that he can still hear their screams today”…

Recently, there has been controversy surrounding SeaWorld’s use of killer whales in shows.
