(1) If this is the case, setal morphology would have a greater effect on force of adhesion than surface chemistry of the seta or substrate.(2) The width of the setal tips also varies between taxa.(3) Only the youngest sporophytes with unelongated setae were used.(4) 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.(5) Spiders, however, have a different adhesive structure at the tip of each leg, formed from a dense aggregation of miniature hairs called setae .(6) Ice worms propel themselves using setae , extremely small bristles that protrude from the sides of their bodies.(7) The krill then squirt the seawater sideways through their setal filters, entrapping algae in a feeding pattern much like the baleen whales.(8) Therefore, capillary forces are strong in the normal direction and weak in the parallel direction, whereas the opposite is true of setal adhesion.(9) Similarly, setae may be simple stalks with single spatulate tips, or they may be sparsely or profusely branched.(10) The angle of the setal shaft was particularly important in achieving an adhesive bond.(11) Each feeding leg, split into two branches, carries stiff bristles and feathery setae .(12) Inside their gill chambers are mats and hair-like setae covered in bacteria.
