Bioluminescence in Florida

Florida’s glowing waterways are one of nature’s most magical shows. On certain nights, every paddle stroke, fish splash, or a gentle wave can light up the water with an electric-blue glow. This phenomenon is called bioluminescence, and in Florida’s lagoons, it is created by two primary organisms: Comb Jellies and Dinoflagellates. While both produce beautiful glowing effects, they differ in size, appearance, and seasonality

COMB JELLIES VS DINOFLAGELLATES: WHICH ONE IS BETTER?

Meet the Summer Glow Makers: Dinoflagellates (Plankton)

Dinoflagellates are microscopic, single-celled plankton. Because they are so small, you cannot see them individually; instead, you see the light they create collectively.


  • Size: Microscopic (invisible to the naked eye).
  • Appearance: Only visible when they flash in unison.
  • The Glow: This is the classic "Liquid Galaxy" effect. When you paddle, the water looks like it is filled with neon-blue sparks, glowing trails, and electric clouds.

Meet the Winter Glow Makers: Comb Jellies (Ctenophores)

Comb Jellies are small, transparent, jelly-like animals that drift through the water. Although they resemble jellyfish, they do not sting.

  • Size: Marble-sized to golf-ball-sized.
  • Appearance: They have "comb rows" of tiny hairs (cilia) that reflect rainbow colors during the day.
  • The Glow: When moved at night, they produce a soft, blue-green pulse of light that looks like a glowing orb or a shooting star in the water. 

Best Times to See Each Type of bioluminescence

Summer & Fall: Dinoflagellate Season

Summer & Fall: Dinoflagellate Season

Summer & Fall: Dinoflagellate Season

  • Peak Months: May - October 
  • What to Expect: Intense, widespread glow. Every paddle stroke creates bright, electric-blue. This is the most popular time for bioluminescence tours in Florida. 

Best Tour for this Season

Winter & Spring: Comb Jelly Season

Summer & Fall: Dinoflagellate Season

Summer & Fall: Dinoflagellate Season

  • Peak Months: October - May 
  • What to Expect: Subtle, scattered glow. Many guests find this season fascinating because you can hold the jellies as they glow. Comb Jellies have no stinging mechanisms. They thrive in cooler water temperatures.

Frequently Asked Questions

 A: Yes. Comb Jellies do not have stingers, and Dinoflagellates are harmless plankton. You can safely run your hand through the water to see the glow. 


 A: The organisms glow regardless of the moon, but darkness is better to see it clearly. New Moon weeks offer the best contrast and the brightest visual experience. 


 A: Absolutely. Clear kayaks provide a 360-degree view, allowing you to see Comb Jellies drifting beneath your seat or the plankton "sparking" under your feet. 


 A: As a natural phenomenon, intensity varies based on wind, tides, and recent rainfall. However, Florida's lagoons are among the most consistent places on Earth to view it, however bioluminescence is never guaranteed.
