A kayaker recently captured stunning footage in the Haulover Canal, a waterway north of Merritt Island, Florida. A hunting dolphin created a blue glow in the sea at dusk.
The most fascinating phenomenon is caused by dinoflagellates, tiny single-celled organisms that caused the water to glow neon blue (see video above). The so-called bioluminescence is responsible for the luminous appearance – the ability of living things to generate light themselves.
The water of the Haulover Canal lit up because millions and millions of dinoflagellates — tiny algae capable of bioluminescence — emit light. As scientists 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 enough if you sail a boat on the water or throw stones into it. Or when a dolphin plows through the water on a hunt…
Algae glow to protect against enemies
Like so many things in nature, the light up has an important function: the micro-organisms light up to protect themselves, so to speak, from irritating fish and other predators. Luminous prey signals danger to potential enemies and sometimes prevent the dinoflagellates from being eaten.
