Tiny organism could have turned a pond in a Maui wildlife refuge a vibrant shade of pink

A physique of salty water on the Kealia Pond National Wildlife Refuge on the Hawaiian island of Maui has gone vibrant pink, presumably as a consequence of a tiny organism, in accordance with federal officers.

The pond on the refuge is presently twice as salty as seawater at 70 elements per thousand, the U.S. Fish and Wildlife Service stated. The preliminary concept is that halobacteria, a single-celled organism that thrives in high-salinity environments, has bloomed and turned the water pink.

“I was shocked. It was like this Pepto Bismol-­Barbie pink, vibrant color,” Travis Morrin, who caught aerial photographic footage of the pond, informed the Honolulu Star-Advertiser.



FWS employees have been monitoring the pink pond since Oct. 30. While halobacteria aren’t harmful just like the algae that trigger the crimson tide, the company continues to be warning folks towards going into or ingesting the pond water whereas ready to verify the coloration’s trigger.

The pond’s hue is unprecedented even for many who have volunteered on the refuge for 70 years, in accordance to the Associated Press.

Refuge employees additionally identified {that a} stream usually flows into the pond has stopped as a consequence of a drought.

Conversely, rain may very well be the important thing to ending the pond’s pink interval. With new water flowing in, the salinity would drop and the quantity of halobacteria would lower, lessening the quantity of coloration within the water.


“That might be what makes it go away,” Bret Wolfe, the refuge supervisor, informed AP.
