setae
Stiff invertebrate hairs
Setae are bristle-like structures found on many organisms.
In earthworms and other annelids, setae are tiny projections that grip soil during movement.
Insects have setae on their bodies—sensory hairs that detect touch or vibration.
In botany, setae are the slender stalks supporting moss capsules.
Singular: seta.
