In a lab tank at the Shirahama Aquarium on the Pacific coast of Japan, a jellyfish smaller than a pinky nail is doing something no other animal is known to do reliably. When the biologist Shin Kubota stresses it — by starving it, puncturing its bell, or shifting the water temperature — Turritopsis dohrnii shrinks, drops to the bottom of the tank, and over the next few days reorganises its adult cells into a juvenile polyp colony, the equivalent of a frog turning back into a tadpole, or a butterfly into a caterpillar.

It also kept the carrier’s logo off the device, left Apple in charge of the hardware and software experience, and included a revenue-sharing arrangement that sent part of an iPhone customer’s monthly bill back to Apple.
