spider with prey ... ... we were fortunate ....:)))
.... the last morning to go to school with my daughter .... .. Passing by a 'huge spider web and as always, remains fascinated ..... ....... from this creative sewing :)...... the moment and it still ..........
The web is a thin cloth made of microscopic wires that spiders secrete in order to trap their prey, usually insects ; is mainly composed of a viscous material that spiders produce through the glands, but can also produce wires that serve as non-viscous structure. The web is particularly resistant, its tensile strength is comparable to ' high quality steel, approximately 1.3 - 1.65 GPa . However, the spider silk is much less dense than steel, and the relationship between tensile strength and density is 5 times higher and comparable to nylon filament aromatic like Kevlar .
CURIOSITY ' ..... Unlike other insects, a spider has jailed a formidable weapon to escape from the prison that has created: eat it. Most spiders weaving is able to remain the silk that produced no consequences for your body.
