• The paper describes the following items ; (a) the construction of orb-web, (b) the chemical composition of secretions and the adhesive materials, (c) the toxin of spider, (d) the courtship and ferromon, (e) the thermal properties of spiders drag line, (f) the change in color of drag line. For example, the toxin of spider contains spermine whose existence is detected in human semen. The DSC curve between room temperature and 600°C shows that the spiders thread should be at least stable up to 200°C. The color of drag line changes from white to yellow with changing seasons from summer to autumn. The fact suggests a possibility that the color of spiders thread protects the spider from foreign invaders.
