Fig. 3. Typical tensile test data for dry MA silk collected from Araneus
and Nephila. Traces were chosen to demonstrate the range of data
collected. Dashed traces are data from Nephila, unbroken traces are
data from A. diadematus. The black circle represents the mean failure
stress and strain for Araneus with error bars representing one
standard deviation. The black square represents the same values for
Nephila. Each sample was from a different spider.
