Silk Spinners
YOU’VE probably seen a spider’s web
before. You might have even gotten caught
in one if you weren’t paying attention while
walking through a park or nature reserve.
Spiders produce the silk to build webs through
small organs called spinnerets. Many spiders
can make at least six different types of silk,
so even if they don’t build webs to catch prey,
spiders also use silk to line their burrows
or as protection for fertilised eggs. Some
spiders build “signal” threads to warn them of
incoming insects; others throw a thread with
a sticky ball at prey to catch them. The young
of some species of spiders even use silk as
“parachutes” to transport them in breezes.
