Spiders
This report deals with testing the toxicity of certain chemicals on spiders, and determining the toxicity by how it affects it's ability to weave it's web. This report contains research on the four chemicals (benzedrine, chloral hydrate, caffeine, and alcohol) as wellas the spiders and their webs. Spiders are of course found in the class Arachnidia, which also contain mites, scorpions, and other arthropods. The order which spiders are classified under is called Araneae, a word of Latin origin. Most spiders are land dwelling, but some can be aquatic. Those that are aquatic spend most of their lives in or around water. Spiders can live in a vast amount of different places around the world. Jumping spiders have been collected on Mt. Everest at a height of 22,000 feet, the highest elevation at which any animal has been collected (Orkin, Insect Zoo 1). Adult species vary greatly in size, which is a contributing factor in the prey they choose, and also the way they catch this prey. Spiders range from less than three hundredths of an inch to more than 10 inches. All spiders are carnivorous in their eating habits, insects being first on their menu. Spiders usually catch live animals because the movement of the p
Chloral hydrate takes about 30 minutes to take effect, and should induce sleep within an hour. Once in the body, it enters the bloodstream, and passes through the stomach lining. Chloral hydrate will not affect respiration and blood pressure when taken at the recommended doses, yet larger dosage can lead to severe respiratory depression and extremely low blood pressure. Spiders can have many pairs of eyes however, this number often reaches four. High doses or injections have the potential to cause a rapid or irregular heartbeat, tremors, loss of coordination, physical collapse, sudden increase in blood pressure, very high fever, and possibly heart failure. Since insects only see in UV light, they might as well fly into a trap (Lyons, Spider Silk 1). Death can result from a BAC (blood alcohol content) of 0. New efforts are currently under construction as more people are finding new ways to use a strong, elastic fiber. (Orkin, Insect Zoo 6) Many spiders secrete a fluid in their posterior abdomens which is later extruded as a silk. Some spiders have been known to kill vertebrate animals, such as fishing spiders, who thrive on small fish, or bird spiders, feeding on small birds from South America, as well as a variety of lizards. Spiders have two main body regions: the cephalothorax and the abdomen .
