Group Presentation Outline Black Widow Spider
General Purpose: To inform
Specific Purpose: To inform my audience of the physical appearance of the Black Widow, the environment in which they are found, and how their venom affects the human body.
Central Idea: Black widows are known to be the most venomous spider in North America with venom more than 15 times stronger than that of rattlesnake's.
Introduction
I. Attention-Getter: Have you ever felt the urge to hurt or kill your significant other?
II. Other: According to DesertUSA.com, the female black widow has been known to injure or kill the male spider after mating.
III. Central idea: Black

. D. Arkive.com states that these spiders like to make their web close to the ground and in a dark, dry place. (Internal transition: We have seen the physical appearance and the environment of the black widow, now I would like to talk about how their venom affects the human body.) III. According to the National Geographic website, black widow spiders are non- aggressive and will only bite if they are disturbed. A. BugGuide.net states that, the bite may just feel like a slight prick to the victim that occurs when the spider's fangs are injecting their toxic venom underneath the skin. B. After bit, swelling and redness may emerge around the general location of the bite. C. After the venom gets in the blood stream the victim may have local pain that can worsen and spread across the body. D. Jessie Szalay, a LiveScience Contributor, states "Contrary to popular belief, most victims do not suffer serious damage"(verbal citation). E. Anti-venom can be found in most hospitals or emergency centers. F. Carol Jorgensen Huston, an RN and professor of Nursing in California, says "Patients who are under 12 or over 60 years old or who are pregnant or seriously ill are especially vulnerable to severe reactions"(verbal
...well, which is how the disease got its name. The swelling then becomes tender, and perhaps as large as an egg. The heart begins to flutter rapidly as it tries to pump blood through swollen, suffocating tissues. Subcutaneous hemorrhaging occurs, causing purplish blotches on the skin. The victim's nervous system began to collapse, causing dreadful pain and bizarre neurological disorders. By the fourth day, wild anxiety and terror overtake the sufferer and then the sense of resignation, as the skin blackens and the rictus of death settles on the body. (Blue).
A defining feature of the lionfish which everyone sees are the “18 venomous spines on its dorsal fin and its pelvic and anal fins, which are used for defense” as described in FACE OFF WITH THE ENEMY: LIONFISH by Special To The Citizen. Which is a neurotoxin that results in intense pain and swelling of one’s body. Fernando Simal, a marine hunter at STINAPA National Marine Park, found out the potency of their venom after his first hunt when being stung by the lionfish he caug...

These things are called ‘biotic factors’, or living things that affect something. In this case, mongooses if mice, the main source of food for the cobra, perish, and us. Mongooses are fast, large rodents that love the taste of King Cobras. They are immune to the venom of the King Cobra, which is actually quite interesting. To the next biotic factor, mice. Cobras love the taste of a plump mouse, but are known to eat other cobras if desperate. But, mice are the preferred diet, and there would be some trouble if they went away. The last biotic factor, is humans. Yes, in China, the King Cobra is a nice meal to eat. Not only do we eat them, but we also confuse them with the snake

People of this time always had body lice and fleas. After bitten by an infected flea, nearly all victims died within three days. The early symptoms were growths the size of nuts that could grow to the size of an apple on the legs, groin, armpit, and neck. The lumps started out being red then progressed into a dark purple or a black. There wer...
When the poison is sprayed at the predator, the predator will slowly lose all functions of it’s body and die within a couple of hours. The organism can detect a predator by using the light, a sensory detector, located in front of its head to check for shadows of possible predators. If this is the case, our organism will turn around and swim in the opposite direction. The organism appears as camouflage, so if the predator is close, it can try to hide. The organism also has sensory detectors on its body, which can sense a pressure change in the
An asp bite creates a particularly awkward, excruciating death. The asp venom causes blood poisoning and an intense burn at the site of the wound. This burning is quickly forgotten, however, as the bite victim fades into a state of giddiness accompanied by nausea and extreme thirst. Blood clots form as the skin becomes speckled with purple spots, and there is usually a considerable amount of swelling. The victim then goes into convulsions, vomiting, urinating, and defecating uncontrollably (Hughes-Hallet 106). This is not a death suitable for a Queen, let alone Queen Cleopatra. Nonetheless, writers throughout history have designated the asp to be Cleopatra's suicide weapon. Her death is described as either an ecstatic orgasm or a serene slip into eternal slumber. Analyzing her death with an eye for accuracy, we can see that it is highly unlikely that Cleopatra would have chosen to kill herself with an asp. "Asp" is an imprecise term, which referred to many various African vipers, all of which would have left her corpse looking less than beautiful. The death that Cleopatra is described to have experienced resembles the death caused by a cobra sting, not an asp bite. A cobra would have had to be at least four feet long to excrete enough venom to kill Cleopatra and her two maids (Hughes-Hallet 107). Since writers have taken liberties with their descriptions of Cleopatra's death scene, representing the asp in various ways, we should ask, "What does the snake symbolize in Cleopatra's suicide, and how does this representation affect the overall portrayal of the Queen and her suicide?"

Scabies mites are distributed worldwide, affecting all races, ages and socioeconomic classes in all climates. Sarcoptes scabei, human itch, or mange mites, are in the arthropod class Arachnida, subclass Acari, family Sarcoptidae. These mites burrow under the skin, living in linear burrows. Other races of scabies may cause infestations in other mammals such as domestic cats, dogs, pigs, and horses. It should be noted that races of mites found on other animals could not establish infestations in humans. They may cause temporary itching due to dermatitis but they do not tunnel into the skin.
The tarantella has a very interesting history. Its name derives from a little southern town of Italy called Taranto. It was believed that if a spider called the tarantula bit the townspeople, the only way to survive its bite was to do a dance called the Tarantella. The locals believed this was the only cure. If the people bitten did not dance they would suffer severe pain, muscle spasms, vomiting; most eventually died.
...rane configurations, and release mediators of inflammation. Most venoms affect the muscle or nervous system, but most human reactions to jellyfish stings are consistent and the severity varies more. (Bailey, 2003) Sponges and Hydroids usually have the mildest venom among cnidarian, with the exception of some species. They usually only result in slight inflammation. Some species of jellyfish will also give a slight sting that causes inflammation. The most severe stings are caused by the Physalia species, scyphozoans, and cubozoans. (Bailey, 2003) These can give stings that cause loss of consciousness, edemas, muscle spasm, heart failure, coma, or death. (Bailey, 2003) This is just a very short list of the symptoms from cnidarian stings. This quick, and effective, firing system combined with potent venom makes many cnidarians the most venomous organisms known to man.
Fact: People that read about the diseases spread by mosquito and tick bites naturally assume that the parasitic bite of a bed bug carries the same potential. However, studies have shown that there's almost no evidence that bed bugs actually spread any of the diseases they carry, such as hepatitis B, hepatitis C, and even HIV. That doesn't mean that scientists are ruling out the possibility of it ever occurring: they've just never seen it happen.
During a bite, an infected blackfly (genus Simulium) introduces third-stage larvae onto the skin of the human, where they enter the bite wound
The first thing for most would be a headache, then chills and fever, and some more common ones were nausea, vomiting, back pain, and soreness. After that you moved on to having swellings and then they’d turn black and ooze. The last thing is bleeding internally and that’s the main cause of death from this disease (Snell). The creature that is responsible for all of this pain and suffering is actually so small that you would need a microscope to see it.
