A few hours ago, something on Yahoo! News caught my attention. Magical photos of bioluminescence near the Kynance Cove on the Lizard Peninsula. Richard Haynes has been the man behind the lens to capture this beautiful view in Cornwall County in England.
Such amazing photos! The bioluminescent planktons coming into life under a starlit sky is sheer magic. Do check the photos when you have the time.
Furthermore, more than 4000 miles away, Kutch in India, is gearing up to promote night coastal tourism. The Mandvi Region of Kutch, known for its bioluminescence sightings, will be the focus of this tourism development.
Also, for the last five years, night trekking from Mandvi to Naila has been a highlight of Kutch tourism in summer.
In the summer season, the temperature of the region drops dramatically at night, creating an ideal scenario for trekking and watching this wonderful natural phenomenon at the bioluminescence beach.
So, from the UK to India, bioluminescent beaches are making their presence felt in the beach tourism landscape of the world, expected to reach $364.95 billion by 2032, according to a report published on Coherent Market Insights.
What Is A Bioluminescence Beach?

A bioluminescent beach is where you can see soft lights of neon blue in the water or on the shallow bay. However, in some scenarios, bioluminescence can be green or red in shade.
You can notice the billowing scene where the ocean is calm and warm. Furthermore, the water of the sea has to be nutrient-rich. Also, a windless condition is essential for the visibility of bioluminescence in the shallow bay or on the water surface.
This bioluminescence looks all the more appealing on a new moon night. Also, once the luminescent waves hit the shore, the bioluminescence remains on the shore for at least two nights.
Mosquito Bay in Puerto Rico is the most popular bioluminescent beach in the world.
Where Is There A Bioluminescent Beach? Why Do Some Beaches Glow At Night?

Now, the most fascinating part! What is the cause of bioluminescence at the beach?
Dinoflagellates, a type of bioluminescent phytoplankton, cause bioluminescence or glowing water in the marine ecosystem.
When these phytoplanktons promote the biochemical reaction that causes the bioluminescence, the same gets distributed in the water by the movement of a marine animal, agitated waves, or the movement of a boat.
To explain further, dinoflagellates emit luciferin boosted by the luciferase enzyme. Luciferin is a light-emitting molecule, and when it reacts with oxygen, it produces light.
This bioluminescence process is very crucial for the survival of these phytoplanktons and the marine ecosystem. Bioluminescence is often the medium of communication, camouflaging, and confusing predators.

Can Weather Affect Bioluminescence Sightings?
Yes, weather can affect bioluminescence sightings. The best experience of bioluminescent sights is only possible when the phytoplankton are clustered on the water surface.
A heavy wind flow scatters the clusters. So, the intensity of bioluminescence goes down.
Also, while rainfall boosts algae blooms, heavy rainfalls make the water and the surroundings murky. So, there will be less visibility.
A high percentage of humidity in the air or a cloudy sky also makes bioluminescence in the water and on the beach less visible.
How To Enhance Your Experience At A Bioluminescence Beach?

Follow these simple tips to enhance your experience at a bioluminescent beach.
- Beaches in remote locations have better bioluminescence visibility because of reduced light pollution.
- In most cases, a sensitive ecosystem grows around these waterbodies and beaches. So, you must follow the instructions of local guides and authorities to avoid disrupting the flora and fauna, and be familiar with them.
What Are The Ethical And Responsible Tourism Practices For Visiting A Bioluminescence Beach?

You must not use plastic bags or leave waste behind while visiting these beaches with bioluminescent properties.
Also, as mentioned earlier, it is important to respect the local wildlife. Moreover, you must follow the designated trails only for strolls and hikes around the sea beach.
Furthermore, follow the swimming restrictions and guidelines regarding the permitted beach activities.
Bioluminescence Beach: Frequently Asked Questions (FAQs)
Here are the frequently asked questions and answers about bioluminescent beaches.
Yes, you can swim in a bioluminescent beach. Bioluminescence is caused by phytoplankton and algal blooms, which are usually harmless.
However, some algal blooms can be allergic, and the local guidelines are the most important regarding the swimmability of the water in a bioluminescent sea. Sometimes, the seawater has other allergens, such as jellyfish.
Moreover, the intensity of the current in the water and other weather conditions at every beach will be different.
Also, in some beaches, like Mosquito Bay in Puerto Rico, swimming may be prohibited to protect the fragile ecosystem.
Bioluminescence, being a biochemical process, is not explicitly harmful to humans. However, jellyfish are also marine animals that cause bioluminescence, and they can cause allergic reactions.
Furthermore, dinoflagellates and some other types of bioluminescent algae can produce harmful toxins such as domoic acid and Saxitoxin. These toxins can cause health issues if they come in contact with human skin or are ingested.
Nausea, skin rashes, stomach issues, and allergic problems impacting the respiratory system are common health hazards of swimming in bioluminescent water.
Moreover, many marine animals eat the toxic algae. The toxins remain in their bodies, and when we consume those animals or seafood, the toxins reach our bodies.
No, you do not need special equipment to see bioluminescence. However, you can have the best experience of bioluminescence sightings by paddling or kayaking through the water.
However, to capture the photos of bioluminescence, you will need professional equipment.
Biloluminous waves can last a day or for several days. There are a lot of variables in determining how long the waves or the phytoplankton will last.
The availability of nutrients in the water, the type of algae causing the bioluminescence, the water temperature, and the predators in the water are major factors impacting the duration of bioluminescence.
Moreover, sometimes external aggressors and weather conditions impact the duration.
Nevertheless, in 2020, The Los Angeles Times reported the presence of bioluminescent waves for many weeks in Southern California.
Yes, you can take photos of bioluminescence. However, you will need professional equipment such as cameras with high ISO settings and fast lenses.
Tripods, remote shutters, and intervalometers are other equipment and accessories used to capture bioluminescence.
Smartphones are not ideal for capturing photos of bioluminescence.
