Sydney may be well known for its beaches and sunshine but it’s also packed with natural wonders. From glow worm caves to hidden beaches, there’s a heap of spectacular sights to discover in the harbour city. Glowing bioluminescence which is an oft seen sight on the beaches of Jervis Bay, has now made an appearance on Sydney Harbour so you don’t have to drive for 3 hours to see the phenomenon with your own eyes.
Bioluminescence has been spotted at Rushcutters Bay and eager Sydneysiders have been flocking to the spot to see the striking event with their own eyes. Although it’s hard to say how long it will be around, you can catch regular updates where to see the event with your own eyes on the Bioluminescence Australia Facebook group where bioluminescent enthusiasts post their adventures daily.
Sightings of bioluminescence are getting increasingly frequent in Sydney and NSW with the glowing phenomenon most recently witnessed on the Northern Beaches in August. Palm Beach, Shelly Beach and Manly Beach are some popular spots where visitors have seen the ocean sparkle in bright hues of blue. But as pretty as the event is to look at, increasingly frequent sightings could indicate that this is happening due to climate change as reported by the ABC.
What causes bioluminescence?
Bioluminescence occurs because of a chemical reaction that produces light in some animals in the ocean. Organisms in the ocean can glow for a number of reasons including changes in the environment, a physical disturbance such as waves or a splash in the water according to the National Geographic Society. Bioluminescence can also be produced to lure prey or search for prey.
Bioluminescent creatures are found throughout the ocean from the surface to the deep sea beds.
