Rare Natural Phenomena Quiz: Bioluminescent Bays & Pink Lakes

First question: What causes some ocean bays to glow neon blue at night?

Is it A) radioactive minerals, B) glowing jellyfish, or C) microscopic plankton?

If you guessed C, you’re right!

Bioluminescent bays light up thanks to dinoflagellates—tiny organisms that emit light when disturbed.

It’s like nature’s own light show, and it’s absolutely mesmerizing.

Next up, which country is home to the world's brightest bioluminescent bay?

Is it A, Australia, B, Puerto Rico, or C, Thailand?

The answer is B, Puerto Rico.

Mosquito Bay on Vieques island holds the record with over 700,000 dinoflagellates per gallon.

It glows so brightly it looks like liquid stars.

Now for something pink.

Why do some lakes turn bubblegum pink?

Is it A, algae, B, minerals, or C, flamingo feathers?

The answer is A, algae, specifically Dunaliella salina, which thrives in salty water and produces a red pigment.

When conditions are right, entire lakes blush pink.

It's not Photoshop, it's science.

Final question.

Which of these pink lakes is real?

A Lake Bubblegum in Canada, B Lake Hillier in Australia, or C Lake Rose in France?

If you picked B, you nailed it.

Lake Hillier is famous for its vibrant pink hue, and scientists still aren't entirely sure why it stays

pink year round.
