We had a great summer in North Carolina in 1993, when dad was visiting Duke University Marine Laboratory. Back then, as a young child, I had little idea what dad got up to, but we got to visit his lab one day. I was amused, confused, and slightly horrified to find fiddler crabs suspended in the air from sticks super-glued to their backs. As they tried to "run" away they would turn little polystyrene balls placed under them, that tracked their movements (or rather, attempted movements!). Poor things! He said he released them eventually... hopefully without the stick.
Over time I encountered similarly inventive experiments... in Sussex, at home... and I grew to admire what a clever and creative scientist he was.
