It might seem that it is the water itself that is glowing. But instead, the glow is caused by millions of tiny organisms called dinoflagellates that live in the water and sometimes make it glow.

These places, called “bio bays,” glowing tiny microorganisms called dinoflagellates. When these tiny creatures are disturbed, they light up the water with a beautiful blue-green glow.

Their populations are distributed depending on sea surface temperature, salinity, or depth. Many dinoflagellates are known to be bioluminescent. Laboratory experiments have provided insight into the ...

Bioluminescent waves glow off the California coast. The phenomenon is associated with a red tide, or ... [+] an algae bloom, filled with dinoflagellates which react with bioluminescence when ...

The bioluminescent bay on the Puerto Rican island of Vieques teems with microscopic life-forms called dinoflagellates, which light up whenever water nearby is disturbed. In the distance ...

At night, the waters emit a blue glow from organisms called dinoflagellates that live in the waters and light up when disturbed by boats, paddles or hands dipped in the water. Hundreds of ...
