Fig. 7. (A) The instantaneous modulus of MA silk is plotted against strain. The
Araneus curve is difficult to distinguish from the axis because of
the relatively high modulus of Nephila. (B) To better distinguish the
Nephila and Araneus curves, the data from A is plotted as
log modulus versus strain. The solid squares indicate the initial
stiffness of Nephila silk, and the solid circles indicate the initial
stiffness of Araneus silk.
