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. Depending partly on their form and function, protostome setae may be called macrotrichia, chaetae, scales, or informally, hairs. The setal membrane is not cuticularized, so movement is possible. Annelid setae are stiff bristles present on the body. They allow earthworms and their relatives to attach to the surface and prevent backsliding during peristaltic motion. https://en.wikipedia.org/wiki/Seta
