I was poking around the UC San Diego Research Affairs site and stumbled on this collection of videos about various natural researves tied to UC San Diego. (The first video I clicked on required some buffering...but it was worth the wait...I learned about a protective seed pod that looks just like a "spiky loofah". The "spiky loofah" is from a plant called a "cucamonga manroot". The video is here: http://research.ucsd.edu/media/video/UCSDResearchVideo.aspx?v2Play=scripps_08.mov
