Strange physical behaviors of filaments

Fibers seemingly acted upon by unseen forces

fibers/filaments plucked directly from the environment. Such fibers are highly prevalent and easily located under the microscope. Although incredibly small and nearly imperceptible to the naked eye, they can be individually lifted and transferred with the use of fine implements such as tweesers or a toothpick. Something about their makeup give them very adherent properties. Some possess small barbs, hooks and tendrils, apparently for purposes of latching and attaching when something moves through their environment. Initial observations of these filaments seem to indicate that they remain dormant/inert until such time as something comes into contact with them. Perhaps physical interactions introduce a static charge of sorts that creates a kind of tension response? The effect of whatever mechanisms are at work seems to be that the filaments will rock, recoil, twist and contort in response to the most minute of environmental stimuli (and sometimes to no apparent stimuli at all). The delicate and challenging nature of isolating these fibers makes the task of observation somewhat clunky, but I believe further investigation is warranted.
