🕷️ How do spiders make silk?
Liquid silk proteins solidify as they are drawn through spinnerets into multi-job fibers.
What you’ll learn
- Glands, spinnerets, and liquid silkExplain silk as liquid protein solidified by controlled drawing through spinnerets.Spiders store silk dope in glands and extrude it via spinnerets. Pull, chemistry, and nozzle geometry turn liquid into fiber on demand.
- Drawing, drying, and fiber jobsDistinguish structural dragline silk from sticky capture silk and the spider’s role as motor.Different glands make different fibers. Dragline scaffolds; capture spiral sticks. Draw rate shapes performance.
- Why silk works — and what we copyConnect molecular composite design, web sensing, and why synthetic silk is hard.Crystals plus stretchy matrix make tough fiber. Webs sense prey. Humans struggle to copy both protein and spinning path.
Questions this course answers
Where does spider silk primarily become a solid fiber?
Spiders store liquid silk proteins and solidify them during extrusion and drawing through spinnerets.
Match each silk role to its job
Glands make recipes, spinnerets extrude them, dragline builds structure, capture silk holds prey.
Order a simplified path from spider protein to human fiber attempt
Copying silk means making protein, keeping it liquid, spinning with alignment, then matching use-case properties.
