Seta
Hair-like structure on living organisms
In biology, setae (; sg. seta ; from Latin saeta 'bristle') are any of a number of different bristle- or hair-like structures on living organisms. Animal setae. Protostomes. Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of chitin. https://en.wikipedia.org/wiki/Seta
