As I mentioned once, my life as a scientist more or less started when I read a book by a woman who built a marine research lab, now Mote Marine Lab in Florida, with her own hands in the 1950s. Among other general awesomeness, Dr. Clark personally dragged 14-foot sharks to a big shark pen to prove that they have color vision, learn surprisingly fast (think golden Retriever, but replace fetch with biting things), use electric fields to make their ‘final approach’ and love the sound of struggling fish almost as much as the smell of blood.
Dr. Clark also struck an early blow for shark conservation when she showed that contrary to the myths of fishermen who slaughtered sharks on general principle, most sharks get along fine with others unless you sound and smell like a struggling, bleeding fish*.
All of this is to say that, granting some artistic license, XKCD pretty much told my story. Also see here.
