A beach in Tasmania is currently glowing, but don’t worry — it’s supposed to be like that.

Preservation Bay turned a bright shade of blue over the weekend, and Instagram was not disappointed.

The glow comes from a bloom of bioluminescent algae, according to Mashable.

“It was very interesting watching this iridescent aquamarine color light up the waves as they crashed,” photographer Brett Chatwin told The Advocate.

The algae are single-cell organisms called dinoflagellates (or “sea sparkle”) which light up when threatened.

According to National Geographic, bioluminescence is both a defense against predators and an aid to help hunters seek their prey.
