Questions this course answers

Where does spider silk begin?

Silk proteins are produced as liquid solutions in glands and solidified through spinnerets.

What is the role of radial threads?

Radials provide structure and carry mechanical signals from impacts.

Why is the capture spiral different from the frame?

Capture silk is sticky, while walking and structural lines are generally non-sticky.

How does a spider locate prey in its web?

Impacts send vibrations through the network to the spider’s sensory legs.

Why do web designs vary among spiders?

Architecture is adapted to local supports, prey movement, and the spider’s strategy.
