| Observation with a hand lens will reveal abundant, characteristically long, brown setal hyphae, 5-10 µm in diameter and up to 3 mm long, with a thickened wall, 1.5-2.5 µm, between the sheets of decayed wood. |
| Therefore, capillary forces are strong in the normal direction and weak in the parallel direction, whereas the opposite is true of setal adhesion. |
| If geckos were to rely solely on capillary adhesion for attachment, setal function could be constrained by relative humidity of the habitat. |
| The angle of the setal shaft was particularly important in achieving an adhesive bond. |
| To find out how the setae release particles, they first took setal arrays from tokay geckos and affixed them to acetate strips with cyanoacrylate gel. |
| If this is the case, setal morphology would have a greater effect on force of adhesion than surface chemistry of the seta or substrate. |
