Helgoland Wiss Meer 18:254–295 In a separate study, the researchers used cameras in the lab to record the burst of swimming activity (the worm’s “nuptial dance”) that occurs when a worm sets out to spawn, and followed it up with genetic experiments. And they confirmed that another molecule is key for the worm to spawn during the right one- to two-hour window — the dark portion of that night between sunset and moonrise — on the designated spawning nights.

Olive PJW, Pillai G (1983) Reproductive biology of the polychaete Kefersteinia cirrata Keferstein (Hesionidae). 1. Ovary structure and oogenesis. Int J Invertebr Reprod 6:295–306 The bristle worm originally comes from the Bay of Naples but has been reared in laboratories since the 1950s. It is particularly well-suited for such studies, says Kristin Tessmar-Raible, a chronobiologist at the University of Vienna. During its reproductive season, it spawns for a few days after the full moon: The adult worms rise en masse to the water surface at a dark hour, engage in a nuptial dance and release their gametes. After reproduction, the worms burst and die. If you take these considerations into account when installing a thermostat, it’ll work much better.
