Over the weekend, bioluminescent plankton along southern Ireland's coastline lit up the ocean water at Fountainstown Beach near Cork City.

Bioluminescence is the production and emission of light by a living organism and is most commonly found throughout marine habitats such as bacteria, algae, jellyfish, and plankton.

The stunning images were captured by locals, including photographer Joleen Cronin, who likened the midnight phenomenon to a "disco."

"The intensity was incredible, each wave splashing millions of sparkles on to the beach," she told BBC. "I was completely mesmerized by the whole thing. It was amazing. When you put your feet in the water it would just kind of explode beneath you."

Fountainstown Beach is well known for its bioluminescent aquatic life, which emit light in response to a disturbance in the water.
