What is the role of major Ampullated protein in spider silk?

Dragline silk is mainly formed by spidroin proteins. It is a type of major ampullate silk and is produced in the major ampullate gland. Dragline silk is used not only to construct the outer frame and radii of the orb-shaped web but also as a hanging lifeline that allows the spider to evade and/or escape from predators.

Can a spider run out of silk?

Likely. But spiders produce silk from specialized glands in their abdomen, so they’ll eventually make more.

Is silk stronger than steel?

In terms of strength-to-density ratio, however, spider silk is far stronger than steel, according to Treehugger.

A strand of spider silk is made up of many smaller strands — thousands to be exact, Science magazine reports.
