- Silk is manufactured inside their body.
- There are 2-7 silk glands depending upon the type of spider.
- Liquid silk is hardened by using their back legs to apply tension to it as it comes out of their body.
- Each silk gland produces a different type of silk, for example:
- sticky silk for trapping prey;
- dragline silk to protect them if they fall by acting as a safety line like a "bungee cord";
- egg sac silk to protect eggs.
