Cribellum

(重定向自Colulus)
Progradungula otwayensis (Gradungulidae) holding a snare made from silk spun from its cribellum

The cribellum is a silk spinning organ found in certain spiders. Unlike normal spinnerets, the cribellum consists of one or more plates covered in thousands of tiny spigots. These spigots produce extremely fine fibers which are combed out by the spider's calamistrum, producing silk with a wooly texture. The fibers are so small in diameter that prey insects easily become entangled in them, without any glue needed. The spiders then bite them before they can escape.
