Quotations and aphorisms by Cheryl Hayashi:
Some spider silks are really strong, but not all of them are. The ones that are really strong can actually rival steel and approach the tensile strength of Kevlar. Thus far, the dragline silk seems to be the strongest.
With all due respect to arachnophobes, I love spiders. Some might call me obsessed, but I've been studying spiders and spider silks for many years now and don't see an end in sight. There is simply too much to do.
