- Spiders, however, have a different adhesive structure at the tip of each leg, formed from a dense aggregation of miniature hairs called setae.
- Inside their gill chambers are mats and hair-like setae covered in bacteria.
- This will take place in a coordinated fashion across fields of setae, thus resulting in a staged detachment process and allowing for controlled weight transference during the locomotor cycle.
- Each feeding leg, split into two branches, carries stiff bristles and feathery setae.
- Ice worms propel themselves using setae, extremely small bristles that protrude from the sides of their bodies.
Synonyms
hair, whisker
1. 1.1Botany (in a moss or liverwort) the stalk supporting the capsule.
  〔植〕（苔藓或地钱中支撑蒴果的）蒴柄

Derivatives

setaceous

adjective sɪˈteɪʃəssəˈteɪʃəs

setal

adjective

The angle of the setal shaft was particularly important in achieving an adhesive bond.
Example sentencesExamples
- If this is the case, setal morphology would have a greater effect on force of adhesion than surface chemistry of the seta or substrate.
- Therefore, capillary forces are strong in the normal direction and weak in the parallel direction, whereas the opposite is true of setal adhesion.
- The krill then squirt the seawater sideways through their setal filters, entrapping algae in a feeding pattern much like the baleen whales.
- The width of the setal tips also varies between taxa.

Origin

Late 18th century: from Latin, 'bristle'.
