Black Widow
Classification
The spider is a wide known organism with a wide influence on life. The Black Widow spider is just one of tens of thousands types of spiders. Southern Black Widow is a common name for the spider which is classified scientifically as K: Animalia, P: Arthropoda, C: Arachnida, O: Araneae, F: Theridiidae, G:Latrodectus, S: mactans. There are 31 differnet species from the genus Latrodectus. This genus is commonly referred to as widow spiders. Other members of this genus include hesperus, varilous, and revivensis (http://www.animalcorner.co.uk/venanimals/ven_spidblkwid.html).
The class spiders belong is Arachnida. Class Arachnida contains one of the defining traits of a spider, having eight legs. Other species included in this class include scorpions, tics, and harvestman. The order that defines spiders is Araneae which contains three suborders that are Mesothelae, Mygalomorphae and Araneomorphae. A specific characteristic to this order is that these species bodies are divided into two distinct sections, the cephalothorax (anterior) and abdomen (posterior). Finally, the genus of the South Black Widow spider is Latrodectus. This genus is famous for having spiders with a poisonous bite (Preston-Mafham 1984).

Physiology

The spider’s body is relatively simple. Similar to the rest of the species in Arthropoda, the spider has an exoskeleton that protects it from its environment. This exoskeleton protects the entire body of the spider that includes two segmented sections (the cephalothorax and the abdomen), as well as the four pairs of legs. An example of sexual dimorphism in the Southern Black...

...itude towards spiders is favorable… Although many people, especially in the West, feel a high degree of revulsion towards spiders and may in fact be frightened by them” (Mafham 1984). Living in the west, we have always been exposed to a fear of spiders in Hollywood movies or sudden reactions when someone sees one. The most important reason spiders are beneficial to humans is the control of insects. Spiders are huge predators for insects such as mosquitos, flies, and others; some which can often carry diseases deadly to humans. In addition to disease control, spider venom and silk can be used to benefit society. The silk has been used in eyepieces for guns or in an attempt to create textiles. The venom has more potential to reach more wide spread success in biotechnology where research shows it could benefit victims of heart attacks or Alzheimer’s disease.
The spider’s web is in a corner connected to the tile wall to wile wall and floor, in such a usual spot and it was miraculous that it kept her alive. The miracle she celebrates through out the essay is the death of the moth you once helped killed as the spider killed the sixteen moths who lay behind her toilet.
ImageText BoxImageOne of the biggest threats to the environment of Ontario is the Gypsy Moth (Lymantria dispar dispar). The species itself is native to Europe and Asia. How this affects us is by weakening trees across Ontario and North America. The first time the gypsy moth was found in Ontario was 1969. The gypsy moth can be found in southern Canada (Ontario), New Brunswick, Nova Scotia and British Columbia. It is known to weaken trees and the caterpillar form live in trees and during most outbreaks its caterpillar feces would fall from the trees to the ground or even on top of humans. The average Gypsy Caterpillar can grow 5-6 centimeters long. With five pairs of blue spots and six pairs of bright red dots on their back. The female moth are white and can fly on the other hand, the male moth are brown and can also fly. The female have a 5cm wing span but male have a 2.5cm wing span. The gypsy moth usually lives in open forests and other forests and take up at least 20% of the space. The Gypsy moth are about 4cm long, tan coloured and can be located on tree trunks, furniture, and buildings. (OFAH Invading Species Awareness Program, 2012)
Spider monkey’s live in the tropical rain forrest and are best known for their incredible prehensile tails. I think it goes without saying that their tails adapted to have dermal ridges that hold and grab on to much tighter than any other prehensile tail in the animal kingdom because they lack functional thumbs, and the tails act as fingertips in replacement. Generally speaking, they hang out in Central and South America but sometimes show up as far away as Mexico. Their epic prehensile tails, long arms and teeny13.25 pound bodies allow them to feast high up in the trees on fruits, leaves, bird eggs and spiders. Although their interaction with the environment is interesting, so is their relationship with one anot...
Earlier in movie, one of the characters described queen wasps as being on the same level as black widows; they are carnivorous, paralyze their victims and kill their mates. They are wrong on a few counts. Wasp stings don’t paralyze victims, neither do black wi...
This fear of the unknown is similar to the one shown in Gordon Grice’s essay, “The Black Widow.” In his essay, Grice explains how his fear of black widow made him curious about them. He once feared black widows because most people associated black widows as deadly animals that kill people. However, once Grice said, “I fell, hands first, into a mass of young widows … In about ten minutes my arms carried nothing but old web and the husks of spiderlings eaten by their sibs. I have never been bitten” (47). This revelation for Grice shows that black widows aren’t what he had thought them to be, but in fact mostly harmless to humans. “We want the world to be an ordered room, but in a corner of that room there hangs an untidy web. Here the analytical
In the short story The Scarlet ibis, the author James Hurst suggests how choices can affect an individual’s life.
Instead, most facts when doing research show that this urban legend may be just that a legend. This is due to the habitat and climate that spiders prefer to live in. According to an article called (spider habitat) spiders are number seven on the list when it comes to animals that are most diverse in the world when it comes to where they can live. Warmer and more tropical regions are where spiders tend to survive and live the best since they are able to find an abundance of food and different forms of shelter (Spider

There is always a certain balance in life that people either knowingly or unknowingly abide by. In this tale, there was a lack of paternal instinct, as well as a lack of the people’s faith in God, both of which led to the birth and rebirth of the black spider. The poisonous black spider was a result of the imbalance of order and as a way to make the villagers pay for their sins. The people need to tell the story of the spider because it serves as a reminder and a lesson to be humble, to put ones trust and faith in God as well as to resist temptation.
The director of Spider-Man (Sam Raimi) has introduced the audience to a feeling of aspiration through a variety of different techniques and captures the viewer’s attention to the smallest details with great success and deliverance to become the character that is Peter Parker.
To begin with, the horseshoe crab, one the world’s oldest living creatures, are quite active. This fascinating crab has ten small walking legs under a strong, sturdy exoskeleton, a long spine in the abdomen, and a long pointy tail in the back used to push itself back up after being flipped on its back (Swinton, 99). Furthermore, horseshoe crabs got their name in an interesting way. The crab’s arc shaped exoskeleton, or shell, was compared to a horse’s shoe (Horseshoe Crab: Saint Louis Zoo). As mentioned before horseshoe crabs aren’t actually crabs. Though it may look like one, they are actually part of a family called Limuli. Some reasons it could have been misconceived as a crab are because its shell is comparable to a crab’s, the legs look a bit similar, and they are found on the Atlantic coast like other crabs. Also we can find horseshoe crab right here in North America along the hot, sandy Atlantic
...er and the soul are alike in how they search for what will continue their existence. For the spider, it is waiting patiently as he tries to find a way to trap his prey in order to continue its life. As for the soul, it must be patient and hold on to what it knows as religious truth as it waits to be nourished by the one that it truly serves. Both the spider and the soul must hold onto their anchor in order to wait for their prey. Once it is spotted, they must move quickly to it in order to ensure that they catch it. Once it is within their grasp, their existence may continue. But, if they are sidetracked by what goes on in their immediate surroundings instead of concentrating on their prey, then they may lose their opportunity for life. That is why the spider and the soul must be patient, noiseless, and ever ready to obtain what they have hunted for so long.
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.
