A threat in the deep



Elliot’s beach on Monday night sported a blue glow called ‘Sea Tinkle’, otherwise known as bioluminescence.



This phenomenon occurs when Noctiluca algae emit light when they are disturbed.



Though people visiting the beach were thrilled to witness the glow, the algae are likely to disturbed the marine food chain, causing fish mortality.
