Very nice tendril, Saul. From what plant?

I like how your "bigger" and stereo images show ridges on the edges of the strand. And I wonder if they are performing a job similar to that accomplished by a copper wire in a tendril simulation published by Sharon J. Gerbode et al? (The three-minute video at that link is interesting--at least for tendril nerds--and somewhat surprising.)

The presence of trichomes on your tendril makes me wonder: Could they be involved in signalling to the tendril that an object has been reached around which it can curl? An experiment suggests itself. . . . Very Happy
