Kogel Bay came alive with glowing blue waters on Sunday, 16 February that looked like something from the sci-fi movie Avatar. This was caused by a type of plankton called bioluminescent dinoflagellates that naturally emits light.
Local Jézelle Fourie posted a video and pictures taken by Eric Nathan to Facebook, later shared by Anele du Plessis:
Bioluminescence is a defense mechanism used to evade predators. The dinoflagellates produce light when disturbed and will emit a flash of light lasting a fraction of a second, according to leisurepro.com.
