Capsules discharged by green bomber worms produce bright green bioluminescence to distract predators.

Edit Hook


“Green bioluminescence occurs in all the “bomb”-bearing species tested for luminosity. The luminescent structures are colloquially termed bombs because they suddenly burst into light when released by the animal, glowing intensely for many seconds then slowly diminishing. Similar autotomy of bioluminescent structures is thought to be a defensive behavior, distracting a predator while the animal escapes.” (Osborn et al. 2009:964)
