Bioluminescent algae bloom dazzles beachgoers on Anna Maria Island

MANATEE COUNTY – It comes as no surprise to locals that the waters surrounding Anna Maria Island in Manatee County hold a brilliant bluish-green hue even on a bad day. But not on this night.

Astrophotographer Tammy Fryer told she recently ventured out to the tip of the island community to capture photos of the Milky Way, something she does whenever the moon doesn’t light up the night sky.

“I’ve seen some spectacular things here, but this is definitely in the top five,” Fryer wrote on Facebook, accompanied by a series of mystifying photos. “No photo or video does it justice. It’s breathtakingly beautiful.”

Fryer caught herself in the midst of a bioluminescent algae bloom.

According to the Department for Environment and Water, a natural chemical process known as bioluminescence allows living things to produce light inside their bodies. Some fish, squid, tiny crustaceans, and algae produce bioluminescence to confuse predators, attract prey, or lure potential mates.

Humans, on the other hand, can witness the natural phenomenon when there is lots of bioluminescence in the water, usually from an algae bloom of plankton.
