The venomous spine is located near the dorsal fin. The poison released from the fin may be mildly poisonous to humans, but it can inflict a painful wound nonetheless. This venomous spine keeps the Chimaera protected from any predator that may come by. They also have another dorsal fin, but the second fin does not have a venomous spine near it. This particular spine can grow to 1.5 m. The head on a Chimaera is covered by a sensory canal which helps it be aware of both prey and predator.
Ocean acidification leads to a reduction in the amount of carbonate ions in the water. Many marine animals essential carbonate ions for the calcium carbonate essential to form skeletons and shells. This will disturb their development and ability to reproduce – ultimately threatening their populations.. Falling numbers of less well-known species, like pteropods – tiny swimming snails – have important effects further up the food chain. Pteropods are important sources of nutrition for many types of fish, whales and birds in polar and sub-polar regions.
Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health. Overfishing is also closely tied to by catch, another serious marine threat that causes the needless loss of billions of fish, along with marine turtles and
Blackfish is a great example of an argument that can be rhetorically analyzed because it has pathos, ethos, and logos. The target audience of this documentary is the general public that includes a big emphasis on the customers of SeaWorld. The filmmakers are trying to inform the public of the inhumane treatment and the conditions that the orcas face while at amusements parks such as SeaWorld. As described in the film, orcas are seen as intellectual animals that are aware of their surroundings. Because of their intellect, orcas don’t belong in a place SeaWorld and should be released.
No more can they hum, for their gills are all gummed. So I 'm sending them off. Oh, their future is dreary,” (Seuss, 1971, p. 53). The humming fish mentioned in the story may not exist in real life, but we are harming actual fish by polluting our rivers with dangerous chemicals. The point is clear: our future may be dreary as well if we continue on this path of pollution and pesticides.
Contrary to the popular belief, bass can actually see colors. Biologists will argue that bass can see red and green colors better than humans can. In waters, colors change depending on the depth they are perceived. Some become clearer and others fade into nothingness. So the color of the lure used is critical, if at all you want to catch the big bass.
She thinks that the accident is all her fault and that she killed her best friend. To sometimes when she sees water she gets nervous and because she was scared of water for a while she got a fish tank. She got the fish tank to help calm her whenever she got on the water. So that whenever she thought about water she can think
Contamination with pathogenic bacteria from the human/animal reservoir can occur when the landing place is unhygienic or when the fish are washed with contaminated water. Upon the processing of fish, its exposure to water is a critical part as pathogens may be present in the water used which can cause contamination and spoilage (Shoolongela & Schneider, 2012). Contamination of food can occur because of problems in food production, preparation, storage or cooking. The aquatic environment and soft tissue of fishes make it extremely susceptible to microbial contamination. Contamination commonly occurs in the environment in which the seafood (fish) is usually caught, during harvesting, and preparation (Wekell, Manger, Kolburn, Adams & Hill, 1994).
In Orlando, Florida yet another event occurred producing the same results, although the common fact remains killer whales were in captivity when these human being were killed. The whales most likely thought these women were fish not people. It is a common misconception of natural instinct and imaginative onlookers; these whales are not people they are wild marine life. It is no secret that killer whales have a bad reputation, however what earned the reputation was sheer unintentional killings. Orinus Orcas are wild marine life that should not be prosecuted like human beings, and the name “Killer Whales” is the result of false
The advertisement also includes the big picture of the fish covering the entire page. The striking colors of the fish compared to the blue of the water behind it evokes emotion towards the fish. The advertisement also includes a picture of fishermen who would be affected if the fish were to go extinct or if fishing was made illegal in this part of the world. All these parts of the advertisement appeal to pathos because it evokes emotion not only towards the people who would starve without their main source of food, but also towards the beautiful, striking fish that would become endangered or even extinct without responsible fishing practices
As humans expand they are producing more waste and need a place for it to go. In some countries, people just pump the waste into the water, as a result it is harming the manatees. The waste that humans are pumping into the ocean is causing toxic algae which the manatee eats and it makes the sick or could kill them. The waste from humans hurts the manatee also by
Luckily, there are potential solutions and ways to control and remove this destructive intruder. Even though physical removal of the fish using nets, traps, angling, electrofishing or biological control by introduction of predators are not likely to be successful for large infestations, they can help control small amounts at a time. In addition to the threat of their predatory behavior and its resulting impacts, there is also a large concern about snakeheads ' transference of pathogens to native fish. Snakeheads carry a disease known as Epizootic Ulcerative Syndrome which can be carried and transferred to the native fish, deteriorating their population. At first, when a fish gets Epizootic Ulcerative Syndrome they will develop red spots on the skin.
and other breeds of goldfish. second is about what you will need for your fish,and a little bit about the actual project itself. This paper will discuss that you can put a fish in cold water and it live. Common goldfish can take cold weather better than other goldfish. they out compete other goldfish for food so you can 't put them together or you will lose your other fish.
Midgley makes no mentions of orcas among the animals she talks about in this article but she does mention dolphins, which orcas are, so I will assume that this would apply to orcas too. Orcas are known to be social beings which means they have emotion fellowship and according to Midgley, this would mean that we must take into consideration that orcas are our fellow-beings. Thus, the way we treat them is terribly wrong and
