Spider silk

Spider silk is a natural fiber produced by spiders, known for its exceptional strength, elasticity, and lightness. Composed mainly of proteins, it is spun into various types of silk used for building webs, capturing prey, or creating egg sacs. Its combination of durability and flexibility allows it to absorb impacts and stretch without breaking, making it stronger than steel on a per-weight basis. Scientists are interested in spider silk for potential uses in medicine, textiles, and materials engineering due to its impressive properties and biocompatibility.
