The aim of this study is to determine if there is a relationship present between spider body weight and spider silk thickness among various species. Discovering the various factors that contribute to differences in spider web characteristics, such as thickness, could help us learn more about the factors that contribute to their extreme elasticity and could be useful for material engineering of a material that is both strong and soft. Previous studies have shown that there is some variation in spider silk diameters, as well as the mechanical characterization of spider-silk. Light-microscopy is a proven method to study the differences between objects that are small, such as spider silk, and will be used in this study to measure the diameter differences. A total of two each from three different species will be obtained. These spiders will then be weighed on analytical scales after exactly four days of feeding to ensure they have the adequate nutrition to spin spider silk. The spider silk will then be measured and compared throughout the species.
