Q

Does the spider have good eye sight?

A

28
Q

What is silk?

A

Silk is a liquid protein that dries as it leaves the spinnerets.

29
Q

How do spiders use silk?

A

They use silk to capture prey, to protect their offspring, to assist them as they move, for shelter, to reproduce, draglines, and egg sacks.

30
Q

A

Ballooning is a dispersal method for a spider line to travel.

31
Q

What types of webs do spiders create?
