The angle of the setal shaft was particularly important in achieving an adhesive bond.
Therefore, capillary forces are strong in the normal direction and weak in the parallel direction, whereas the opposite is true of setal adhesion.
Similarly, setae may be simple stalks with single spatulate tips, or they may be sparsely or profusely branched.
Spiders, however, have a different adhesive structure at the tip of each leg, formed from a dense aggregation of miniature hairs called setae .
The krill then squirt the seawater sideways through their setal filters, entrapping algae in a feeding pattern much like the baleen whales.
Each feeding leg, split into two branches, carries stiff bristles and feathery setae .
Only the youngest sporophytes with unelongated setae were used.
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.
If this is the case, setal morphology would have a greater effect on force of adhesion than surface chemistry of the seta or substrate.
