02.08 Support Your Main Ideas Jellyfish are monsters of a sort. Jellyfish can distort things and shut down whole systems of government when they come in swarms. There are several types of jellyfish but one can have devastating effects. The everyday monster of the jellyfish causes fisheries to lose money, clogs power systems to shut down due to the masses of them and can shut down water filter systems. Jellyfish affect other fish and will kill people easily with their sharp points. Their tentacles are deadly weapons when jabbed with their points. The problem can be solved when the natural ecosystem is the same and jellyfish eats their prey.
They have a strong presence when traveling together based on their weight and size. Jellyfish can
The movie that shocked thousands of Americans with the secrets of SeaWorld became one of the most talked about movies of its century. Blackfish came out in July of 2013 with shocking evidence of the mistreatment of Orcas, also known as killer whales, and the dangers imposed on the whale trainers. The movie had several strategies to appeal to its audience. These strategies included the three pillars of writing; logos, ethos, and pathos. Although the overall theme of Blackfish was to inform the viewers of the treatment Seaworld imposes on Orcas, the fundamentals of the movie actively used the three pillars; ethos, logos, and pathos to effectively catch the attention of the viewers and keep them drawn into the movie; the most prominent pillar was pathos followed
The manipulation of the environment by humans is the first factor that has begun to promote the jellyfish dystopia. As humans change the environment, conditions are beginning to favor jellyfish. In an environment that largely favors them, a population explosion and accompanying jellyfish dystopia is inevitable. These population explosions are a great leap toward the jellyfish dystopia. Throughout the marine environment, humans have begun overfishing in multiple marine environments. This opens niches in the oceanic food webs. These niches, or spaces in the food webs, result from the removal of predators that would previously control the jellyfish population (Stone). In the absence of their predators, the jellyfish population is free to expand and forms blooms, or large jellyfish populations. The jellyfish themselves then prevent the native fish population from rebounding by feeding on the fish eggs (Stone). Human proceed to fish in these areas again, and the jellyfish predation decreases to a greater degree. Humans also improve conditions for jellyfish as we allow pollution levels to rise. Devices like cars are contributors to the carbon dioxide levels. As the CO2 levels rise, this also affects the oceans. They slowly are becoming more acidic and becomin...
waters. They have venomous spines that can be very painful. The Red Lionfish can be aggressive
The Longlure Frogfish can be found in the tropical western part of the Atlantic Ocean next to sea sponges. It is disbursed from Bermuda and the Bahamas to the coasts of the central and south America. It is referred to as a frogfish because of its similar characteristics compared to those of a frog. The Frogfish has really thick skin and highly modified scales called dermal spicules. It is round and short, generally growing up to 11cm. Since one of their main purposes is to prey for food, they rarely use their fins to swim and instead, they have fins that act as feet which help them walk across the ocean. It has very small eyes and a large mouth pointing up which helps them eat their prey. Their big mouth allows them to eat big animals. Usually,
Their group name is smack and they are invertebrates. They group up around the western shore before sunrise, and around 6 am, they start swimming east towards the sunlight. Once they have almost reached the eastern shore, they stop so that they are not under the trees shadows, where their primary predators live, anemones. In the afternoon, when the sun slowly slips back towards the western shore, the jellies follow, awaiting there until dawn. This daily migration is also beneficial for the lake. As the jellies swim back and forth, they churn the water that contains nutrients and small organisms that are the base of this ecosystems food chain. These jellyfish don’t just like to bask in the sun, they need it to survive. Algae lives inside them called zooxanthellae. This algae provides the jellyfish with energy by using
They affect it by maintaining balance in the sea’s food chain. Leatherback turtles rely on huge quantities of jellyfish for nutrients, they are known to eat almost 200 kg of jellyfish per day. Without these turtles the world’s seas would be abound with jellyfish and, since jellyfish feed on fish eggs, this would further hasten the decline of worldwide fish population. (OCEANA, costaricaturtles) However, the Pacific population of leatherback turtles have declined with 90% the last two decades, due to commercial fishing. (seeturtles)
Seaworld is a giant marine life theme park. The greatest attraction to these many theme park would be those killer whales. In fact, these killer whales are the face of the park. As gigant as these mammals are, seaworld is keeping them in some pretty tight quarters. Mr. Jett and Mr.Ventre says “Wild killer whales can swim a hundred miles daily as they socialize, forage, communicate, and breed. In stark contrast, with little horizontal or vertical space in their enclosures, captive orcas swim only limited distances, with most spending many hours surface resting.” The animals don't have the freedom they need. Also when taking the whales out of their natural habit the whales tend to be depressed and not as heath in that situation. They need their freedom in the big ocean blue. Bring them into the small living units, breeding whales in captivity all for the entertainment of humans. At young ages the calves are taken away from their mothers on to a new seaworld park. Mothers of the calves have even been seen denying their offspring.
They live at the bottom of shallow waters and in warmer areas. The clownfish don’t live alone, though. They live in and alongside sea anemone, a marine animal that looks less like an animal and more like an aquatic plant. The colorful tentacles that make up the sea anemone attract different types of marine life that it then shocks and immobilize before consuming the paralyzed creatures.
In response to your second question, I believe that animals still experience pain. Although lobsters do not produce endorphins to help them handle intense pain, it does not mean that their pain receptors are absent all together. For example, some point out how pain is subjective. They claim that lobsters do not experience the same pain we humans do, and they go on to say that the creatures might not even mind the pain. However, this begs the question: why do they try to climb out of the pot of boiling water? If they truly did not mind the pain, wouldn’t they just relax in the boiling water as they are burned alive? Therefore, I think pain is the correct term in this case. So much so that we even realize, deep down, that we are hurting them.
Since nearly the beginning of human history fishing has been an integral part of the culture and survival of coastal communities. These coastal communities and cities have always been some of the most prosperous and successful because of the added resource of the ocean. In the beginning many areas were so densely populated with fish and shellfish that often a day’s worth of food could be caught by simply wading into the shallows. For example, some of the first English settlers to see the Chesapeake Bay described “The abundance of oysters is incredible. There are whole banks of them so that the ships must avoid them. . . . They surpass those in England by far in size, indeed, they are four times as large. I often cut them in two, before I could put them into my mouth” (Miller). This abundance had every appearance of being as infinite as the ocean that produced it but the reality was far different. Many fish stocks, including the oyster, stayed near these high levels even into the beginning of the industrial era. However the new rapid pace of technological advancement proved too much for many stocks to handle. Close shore stocks took most damage as they were the easiest to exploit. Those same oyster colonies that were once an obstacle for boats were nearly eradicated by “the 1890s harvests began to decline. Many oyster beds were destroyed and reefs had been mined away. By the 1920s, the boom was over…” (Miller). While catastrophes like this inspired many sustainable practices there are still fisheries worldwide that are headed for a similar end. Through ignorance and misinformation from the fishing industry most of the general public does not know that this is occurring. The following will serve to inform about the t...
Overfishing is defined as a form of overexploitation where fish stocks are brought down to unacceptable levels. In the UN Food and Agriculture Organization’s 2 yearly report (SOFIA), it states how over half of the fish stocks, worldwide, are fully exploited. Other research has shown it only takes 10-15 years of industrial fishing to obliterate a tenth of the intended specie. Overfishing causes a ripple effect that hurts the entire ecosystem. The balance of chain depends largely on the interaction between the predator and the prey. For example, if the larger fish are removed than its prey begins to overpopulate, due to the lack of population control. The balance in the oceans are a urgent problem, around 90% of predatory fish stocks are depleted. The ripples can extend even further to land creatures like
Many of the methods used in commercial fishing are very destructive to the aquatic systems. Industrial ocean trawlers scrape the bottom of the water, often dragging up the seafloor with them. This destroys the habitat and kills many of the bottom dwelling organisms that are vulnerable to these practices. There is also a large amount of marine animals that are unintentionally caught by the large nets. These animals are considered bycatch, having no value to fishermen and are usually killed. These large fishing vessels also add a significant amount of pollution to the water. Fishing vessels cause oil spills as well as discharging chemical elements and wastes into the water. The thousands of of trawlers that pass through Japanese waters create large quantities of water pollution that can devastate aquatic life by changing the chemical composition of the water and affecting all the organisms that inhabit these
This is a major problem that the reef ecosystem faces (Bellwood, Hughes, Folke, & Nyström, 2004). This is no more apparent than in Thailand 's gulf, were the fishing industry is producing about 2, 3 million tons of fish and shellfish in 2007 (FAO
Clincher: Unless we change the way we view our oceans, jellyfish might be the only seafood on the menu in the near future.
Have you ever wanted to slap eight people at once? Or if you're more of a mushy, touchy, feely person, have you ever wanted to hug eight people at once? An octopus can do either or both of these if they want to! So you know an octopus is lucky being able to do this but what's an octopuses habitat? Since they can slap eight things at once do they have predators? Or since we're on the facty facts subject where do they live?
