Not all cnidarians are known to be killers, but some cnidarians are among the most dangerous marine species known to man. Cnidarians look like delicate creatures, but the potent toxins injected into their prey can kill within minutes. The severity of a sting is determined by the species of jellyfish, the thickness of exposed skin, and the sensitivity the victim has to venom. If stung, you should not panic but find medical attention right away. You will want to wash the stung area with salt water, because freshwater will stimulate the nematocysts again. The best thing to inactivate the nematocysts is vinegar and alcohol. There are also a variety of other sources that can reduce the effect of the sting such as meat tenderizer, sugar, plant juices …show more content…
The Portuguese Man of War, also known as Physalia physalis, is often found in warm waters of the tropics, subtropics and Gulf Stream and is armed with thick nematocysts that can reach up to 165 feet. The Portuguese Man of War has a translucent blue, pink gas filled body that reaches lengths up to 12 inches long. The poisonous creature got its name, because of its appearance to looking like the sail of a Portuguese battleship. The sting of a Portuguese Man of War if very painful, but not deadly. The pain is to be described as putting hot charcoal on your flesh. The pain of the nematocysts can last for hours and can cause welts and red marks to cover the areas the tentacles had touched. There are also symptoms of nausea and difficulty breathing. This particular jellyfish is not considered a “true” jellyfish. In fact, The Portuguese Man of War consists of modified feeding polyps and a reproductive medusa called a float. Since the jellyfish is not a fast moving carnivore the diet of a Portuguese Man of War consists of eating small fish or other creatures it can get ahold of. The nematocysts will paralyze the prey which then will be consumed by the jellyfish. Because jellyfish are venomous most marine animals cannot eat them but there are a few exceptions. For example, sea turtles love to eat the Portuguese Man of War. Other jellyfish are preyed upon by spadefish, sunfish, and loggerheaded
The poem, To the Mercy Killers, by Dudley Randall is by far a poem which tackles the subject of euthanasia right up to its target: the “Killers”. The “Killers” are unfairly portrayed in a negative light, evoking pity for the terminally ill. For most, it is the cause of so much division in terms of beliefs evolving into a never ending moral dilemma, being the natural victims of the absolute conditioning of society. Euthanasia or mercy killing is a confusing subject that tackles the moral, legal, medical and ethical issues. It’s so confusing that even the Randall is somewhat baffled too, about which side to take, although the last line settles everything with: “Do not put my life. Let me still glow” (14), when there is nothing bright about the idea of being robbed off, of the life as a human.
Known as Pterois Volitans in the animal kingdom, also called the red lionfish, is a sight to behold in the tropical waters as they swim like an underwater butterfly in the sea. In waters not native to their origin, as they are from the Pacific and have predators that will have them for a snack. Invasive to the Caribbean Sea they have rapidly reached the Gulf of Mexico and far south, spreading to parts of South America. The lionfish has become a persistent pest that’s more trouble than what it appears to be, attractive yet deceptive with a striking pattern of white and red stripes. In the New York Times article, A Call to Action… and Even Rodeos, scientists say that, “from 2005 onward, lionfish have become the most numerous nonnative invasive species in the world.” The average pound fish is one of nature’s clever creations, a venomous foe with spines and an infinite appetite that reproduce quickly. Invasive species are notorious because they have no or almost nonexistent natural predators and they are adapt to their new home very well. The biological adaptations of this fish has caused both ecological and economical mayhem, serious measures have been taken up to control their population as well as to protect our coral reefs.
Narwhals Introduction Narwhals, the unicorns of the sea, are very mysterious creatures that are not widely known. They are whales with many fascinating features and historical value. This research paper answers the question, “What are Narwhals?”. General Description Monodon Monoceros, Latin for “one tooth, one horn”#; or Narhval, Norwegian for “corpse whale”, because its mottled coloration suggests a bloated corpse#. Narwhals are in the white whale family, along with the beluga, but are actually covered with spots of black, white, gray-green, and cream.
Lionfish have brown and white stripes covering their body (NOAA, 2011). Lionfish have broad pectoral fins, and long individual dorsal spines that contain the venom glands in the tips (NOAA, 2011). The venom of the lionfish is only intended as a defense mechanism and not meant to kill. The spines of the lionfish deliver a sting that can result in severe pain, respiratory distress, and even paralysis (NOAA, 2011). Lionfish are found in almost all tropical marine habitats consisting of warm waters due to their invasive behavior. Their native range covers a very large area from western Australia and Malaysia east to French Polynesia and off the east coast of Australia to the Kermadec Islands of New Zealand (NOAA, 2011). Lionfish have been found along the coast from Florida to North Carolina. The first lionfish was reported in South Florida waters in 1985 with additional sightings occurring until they were documented as established in the early 2000s (NOAA, 2011). Lionfish are very popular aquarium fish, especially in the U.S making them important to the aquarium trade. There are two possible ideas about how the lionfish were introduced into the Atlantic. The first is through ballast water, the water carried in the bellies of the enormous transport ships of intercontinental trade (Whitney, 2003). Larval lionfish have low oxygen and food needs which makes surviving movement in ballast water a possibility (Whitney, 2003). The second possibility is that a number of...
“Taxonomically speaking, a lobster is a marine crustacean of the family Homaridae, characterized by five pairs of jointed legs, the first pair terminating in large pincerish claws used for subduing prey…. Moreover, a crustacean is an aquatic arthropod of the class Crustacea, which comprises of crabs, shrimp, barnacles, lobsters, and freshwater crayfish” (Wallace, 55). This is an example of Logos since the author uses scientific facts to convey the message he wants to communicate in an objective way. Wallace also uses logos as a persuasive device by presenting facts on the science of the lobster’s neurological system and its ability to feel pain. The Maine Lobster Promotion Council states “The nervous system of a lobster is very simple, and is in fact most similar to the nervous system of a grasshopper. It is decentralized with no brain. There is no cerebral cortex, which in humans is the area of the brain that gives the experience of pain”. Wallace counter-argues this statement by mentioning the fact that since lobsters have a simpler nervous system compared to humans, they are unable to produce their own natural opiates. “One can conclude that lobsters are maybe even more vulnerable to pain, since they lack mammalian nervous systems’ built-in analgesia, or, instead, that the absence of natural opioids implies an absence of the really intense
There is a squid-like monster seen off the coasts of Norway that is a mile and a half in circumference named a Kraken. Legend says these creatures have the ability to squirt their blinding venom into the victim’s eye to cripple them. (...
During post the World War 1 era, racial discrimination and violence spread throughout Florida and the United States. White Americans lashed out against African Americans by using unprecedented violence, and consequently wiping out whole communities. In one of the first documented race riots in America, a violent mob, armed with an excuse, massacred the residents of Rosewood wiping the town off the map.
We started to touch them and the starfish had such a unique texture. Afterwards, we washed our hands and headed outside and joined a line that was heading into a big, blue tent. We went inside and we were both surprised and excited to see tons of different-looking and sized stingrays swimming graciously throughout the pool. Everybody leaned over and reached their hand in the water, hoping that their hand would touch a back of a stingray. At first, I was scared to put my hand in the water because I didn’t want to accidentally touch the tail of the stingray even though they removed the barbs so they couldn’t sting you. Kristen didn’t have any trouble touching them, but for me on the other hand, it took a little longer. Kristen really wanted me to touch one so she grabbed my hand and slowly put it into the water. Having my sister there with me made me feel a lot less scared. We saw a small stingray heading our way, so Kristen lowered my hand and then my hand touched the back of the stingray. I was surprised of how smooth it was. It was as smooth as a fleece blanket. I was really happy at the end that Kristen encouraged me to touch one. After that I was able to touch a few more, except there was a big black covered sting ray with white spots that was probably five times bigger than the rest of them, that I was scared to touch and so was Kristen. We exited the tent and got our picture taken with the view of the city and Lake Michigan.
Mass murderers are a danger to society. These killers are malevolent monsters with the desire to kill, and they are nothing new to the general public of today. According to the FBI, mass murder is defined as the killing of 3 or more people on the same day or in a single event. Such killings are rare in the sense that 96% of murders have only one victim while less than 1% have 5 or more. One question that people may have is, “What goes on in their mind?” or “Why do they do this?”. What makes a murderer a murderer is their type, traits, motives, and methods.
Assassinations have been occurring in the United States since the beginning of time. They are usually triggered by religious, governmental, or military intentions that want to harm a political figure. An act that may be completed for commercial gain, from an aspiration to obtain recognition, to punish a grievance or notoriety, or military or security services force people to carry out the horrible killing. John F. Kennedy, Robert F. Kennedy, Malcom X, and Martin Luther King Jr. were all widely inspirational men that were assassinated. These four men were killed for a sole purpose, they were killed to make a point. The killers were all majorly angry, they wanted prominence, and they did not believe in how everything was turning out to be. They were four innocent men that were trying to make a difference in the world, but were killed due to the fact that they wanted purely wanted change to be brought to the world.
A society is an organized group of individuals. In the novel, The Chrysalids, by John Wyndham the Sealand society and Waknuk society are both similar and different in the way they live. The Sealand and Waknuk societies are both egocentric and ignorant, but the Sealand society accepts changes, where the Waknuk society does not accept change and would rather stay the same.
As I mention above the four key features of the typical homicides is that the criminals do not plan their crime but here is contradictory, some homicides are plan like serial killers. Serial killers plan their crime, it might not be all the way through but to an extend they plan their crime. Serial killers follow the three steps on how they kill. First, they interpret the scene and the behavior of the target in a specific way. Second, they transform their emotions into an action and third, the killer needs to uphold his or her behavior (Katz, 1988). No matter how they plan their crime, every crime or every kill has a background or a history to it. Whatever the circumstance may be, there is always an emotion that is presented through the whole process of the killer. For example the serial killer, Dr. Harold Shipman, one of the worst serial killers of United Kingdom. He was the suspect of 250 victims over the period of his 28 years doctor career. He would inject his patients with diamorphine (also known as heroin, it would made the patient feel high, relax and they would not know what ...
The major thing about Mr. Wallace’s article is his concern about suffering of Lobster which he briefly explain the facts, he’s article feature the Maine Lobster Festival in Maine which the festival will cook 25,000 pound of lobsters, the World Largest Lobster Cooker as they call it, lobster will be cook in a gruesome way which he is concerned. Mr. Wallace characterized the lobster that boiling them is really hard for him to watch. Example is in his article he said that “Lobster looks like they are suffering as they hang their claws in the pot”. But this explains why the violent reaction of lobsters to boiling water is a reflex to noxious stimuli. And to add, Based on review by the Scottish animal welfare group Advocate for Animals released reported, a scientific evidence that strongly suggests that there is a potential for lobsters to experience pain and suffering. This is primarily because lobsters and other decapod crustaceans have opioid receptors and respond to opioids analgesics such as morphine in a similar way to vertebrates, indicating that lobsters' reaction to injury changes when painkillers are applied. The similariti...
In John Grisham’s essay “Unnatural Killers” he weaves a story of two love-struck teens (Sarah Edmondson and Benjamin Darras) on a killing spree that claimed the lives of one of Grisham’s close personal friends (Bill Savage) and the mobility of another woman (Patsy Byers). Grisham claims that these teens were influenced by Oliver Stone’s film Natural Born Killers and that “there exists a direct causal link between the movie Natural Born Killers and the death of Bill Savage”(577). Even though I must concede some of Grisham’s points, I still think that, whether the movie (Natural Born Killers) had an influence on the two teens or not it’s still their personal choices to shoot those people. The blame should be laid on Darras and Edmondson because of their decisions, not Oliver Stone because of his movie’s possible influence.
...very painfully (obviously). Cyanide acts quickly, but only large amounts are deadly. Cyanide poisoning can be treated with inhaled amyl nitrate, intravenous sodium nitrite, and sodium thiosulfate. Then there is the most commonly known nerve agent, Sarin. Sarin is clear, colorless, tasteless, and lastly odorless. It's a highly unstable chemical and is for the most part an inhalational hazard. The effects of Sarin poisoning include having a runny nose, tightness in the chest, breathing difficulty, and nausea and vomiting, reflex bowel movement and urination, unintentional muscle movements, intense migraines, confusion, and tiredness. If untreated, victims stop breathing and die. Antidotes for Sarin when affected are atropine and pralidoxmine. Eyes and skin should be flushed thoroughly if exposed. And lastly, there is the most commonly known choking agent, chlorine.
