"For me, each day begins and ends with wanting to learn a little more about the secrets of spider silk. Spiders have been around for over 300 million years and are found in nearly every terrestrial environment. There are more than 40,000 species living today and each spins at least one type of silk. However, most spiders spin more than one type of silk. For example, the orb-web weaving spiders that are commonly seen in gardens during the day or near porch lights at night, typically make seven kinds of silk. Each silk is chemically and functionally distinctive."
