What is bioluminescence?

Bioluminescence is the production of light by heaps of microscopic algae or plant plankton. They get their glow on when they get disturbed by a wave or a predator.

When’s the best time to see the sea sparkle in Tasmania?

Luckily you have a chance of seeing the sea sparkle year round! The glowing plankton is most common in warmer months, but can still be seen throughout the year. Your best bet is on a warm, cloudless day, straight after some heavy rain. Obviously it needs to be dark to see the sea glow, but here’s a crazy fact – most bioluminescent organisms can tell if it’s day of night, so won’t glow during the day even if they’re collected and out in a dark room. Crazy, right?! During the day the plankton give off a pink colour, so if you spot this make sure you head back out at night time to see if they glow.

Can you swim in bioluminescent water?

Sea sparkle contains a lot of ammonium which is known to cause skin rashes and breathing problems. Swimming in bioluminescent water also mucks up the effect by disturbing the algae. So play it safe and marvel at the iridescent sea from the safety of the shoreline.
