Bermuda fireworm (Odontosyllis enopla)  

 

 

The dazzling light display of these tiny bioluminescent worms—barely two centimeters long—had us, for two nights in a row, hopping onto Yavor Dimitrov’s little scooter with Nelly Olova and heading to a familiar bridge in Bermuda to wait for their magical appearance.

The best time to witness the spectacle is two to three days after a summer full moon, about an hour after sunset. Nelly had done her research, and on the second evening we were ready—eyes fixed on the still waters of the bay, waiting for the wonder to unfold.

And then it happened. Exactly fifty-five minutes after the sun slipped below the horizon, the first “fireworks” lit up the water: greenish clouds of luminescent dust swirling in circles. These were the females, leaving their tiny tubes on the seabed and releasing eggs in a graceful, dance-like motion.

Moments later, the males appeared. With their intricate eyes, they caught the glow of the females and darted toward them, leaving a sparkling trail in their wake.

After precisely fifteen minutes, the show was over. The worms shed the bristles that had lifted them to the surface and drifted back down to the ocean floor, where they would begin building new little tunnels—new homes.

Such extraordinary little beings—insignificant against the vastness of the Atlantic, yet astonishing us with their luminous dance of life.
