A few years ago, in a laboratory at the University of Wisconsin at Madison, I walked into a mostly dark room, with a single light illuminating a plastic cup. Within the cup were dozens of tiny white blobs, each smaller than a pea. They were baby Hawaiian bobtail squid, and they were adorable. Their diminutive arms trailed behind them as they bobbed in the water, and the pigment cells that would eventually allow their adult selves to change color gave their infant faces a freckled appearance.
