Spider silk - cribellum


Some spiders have something called a cribellum instead of just normal spinnerets.
When they make silk, it comes out as very tiny string which gets all wrapped around itself and looks almost like it is made of wool.

Because the silk is so tiny and all bunched up, insects get tangled up in it and the spiders can go capture them.
