Foggy mornings enhance spiderwebs' delicate beauty. The intricate architecture only looks fragile. Although spider silk is so light that a strand long enough to circle the globe would weigh only a pound, it has a tensile strength greater than high-grade steel and can stretch to 40% of its length without breaking. Spiders manufacture silk in abdominal glands called spinnerets.  Each spinneret produces a different kind of silk for anchoring, temporary scaffolding, making protective egg sacs or trapping and wrapping prey. Scientists have analyzed the molecular structure of spider silk and are working to reproduce it in the laboratory for practical uses from bullet-proof vests to artificial tendons. Helping spiders thrive by leaving their webs intact is another way to KEEP IT WILD.
