What you’ll learn
- Silk from the abdomenExplain how silk glands and spinnerets produce specialized threads.Spiders use several silk materials and controlled outlets to place fibers precisely.
- A geometry of linesDescribe how frames, radials, and spirals organize an orb web.Web geometry creates a load-bearing surface and sets the spacing of the capture grid.
- Tension carries informationConnect tension and elasticity to sensing and impact absorption.Tension transmits vibration while elastic, adhesive silk helps manage collisions.
- From contact to captureTrace how web contact becomes prey retention.Adhesion, deformation, vibration, and spider behavior work together in a constrained design.
Questions this course answers
What is the main role of spinnerets?
Spinnerets are movable outlets that help guide and combine silk fibers.
Why does an orb web use both radial lines and a capture spiral?
The two networks contribute different structural and capture functions.
What can a spider learn when prey vibrates a web?
Connected, tensioned threads transmit mechanical signals that help locate a disturbance.
Why is a spider web best understood as a compromise?
Web design balances interception and retention against material, construction, and environmental constraints.
