Life Cycle
of a
Spider
How does a spider catch it’s prey?
•Spiders actively search for their prey, hide and
wait for them to pass.
•Build webs to trap flying insects.
Silk is a liquid which hardens when
exposed to the air. Silk is used to
construct webs, safety lines, and egg
sacs, and is used as parachutes for
traveling long distances.
