In May-Septem­ber, you can ex­pe­ri­ence a spec­tac­u­lar light show in the North At­lantic off Ber­muda three days after full moon and 44 min­utes after sun­set.

Worms light up dur­ing their 10-30 minute mat­ing. Fe­males swim in cir­cles, spawn­ing eggs into the wa­ter, while males fer­til­ize the eggs with se­men.

The light is pro­duced, be­cause a chem­i­cal re­ac­tion con­verts chem­i­cal en­ergy in the an­i­mals into light. The bi­o­lu­mi­nes­cence phe­nom­e­non also ex­ists in other an­i­mals such as fire­flies and deep-sea fish.
