This book was originally published in 2002. Elastic proteins occur in a wide range of biological systems where they have evolved to fulfil precise biological roles. One of the only books to treat the whole spider, from its behavior and physiology to its neurobiology and reproductive characteristics, Biology of Spiders is considered a classic in spider literature. Spider silk has been hailed as nature's super-fiber based on its mechanical properties. Extensibility: Needless to say, spider silk is highly extensible, which means that it can be stretched five times its original length without snapping Toughness: The incredible strength and ductility give spider silk tremendous toughness.Its toughness is equated with that of “commercial polyaramid (aromatic nylon) filaments, which themselves are benchmarks of modern polymer fibre technology”.

Spider silk belongs to a class of materials called “biopolymers” which are protein-based materials of biological origin. The silk that spiders use to form the spokes of their web is called dragline silk, and it’s tough, lightweight and biodegradable. These unique materials have prompted efforts to explore potential applications of spider silk equivalent to those of silkworm silks, which have undergone 5000 years of domestication and have a variety of uses, from textiles to biomedical materials. The gland stores silk protein in liquid form, which isn't particularly useful for building structures like webs. Each genetically modified goat at Utah State University produces about an ounce of the spider-silk protein per milking session. First clinical applications of spider silk as suture material go back to the 18th century. Spider silk is useful for a variety of biomedical applications: It exhibits mechanical properties superior to synthetic fibers for tissue engineering, and it is not toxic or harmful to living cells.
