A circadian clock must be self-sustained and internally driven, as the 20-hour cycle of the jellies’ spawning is. It must also be regulated by an environmental stimulus such as light; while the jellies’ spawning clock can run on a 20-hour cycle under persistent light in the lab, in nature it resets every day. And a true circadian rhythm, like ours, should also be unaffected by temperature. In Kitsui’s experiments, however, warmer water made the 20-hour clock faster and cooler water made it slower. It is a molecular biological clock, but not in the way scientists typically define them.
