On the coast of Brisbane, the capital of the Australian state of Queensland, beachgoers recently observed a very fascinating phenomenon after dark: dinoflagellates, tiny single-celled organisms, made the surf glow neon blue in the dark (video above). The so-called bioluminescence is responsible for the luminous appearance – the ability of living things to generate light on their own.
The waters of the Coral Sea, a tributary of the Pacific Ocean, glowed as billions upon millions of dinoflagellates — tiny algae capable of bioluminescence — emit light. As researchers have discovered, the glow is a response to mechanical stimulation.
The tiny protozoa respond to changes in currents and waves by emitting neon-blue light. But it is also sufficient if you float a boat over the water or throw stones into it (see video above).
Algae glow to protect from enemies
Like many things in nature, lighting has an important function: the microorganisms light up to protect themselves, thus irritating fish and other predators. Luminous prey signals danger to potential enemies and sometimes prevents the dinoflagellates from being eaten.
