Mesmerising neon blue waves washed up on an empty Mexican beach as the country's tourism sector was decimated by the coronavirus pandemic.
The incredible scene was caused by millions of bioluminescent plankton crashing against the shore in Acapulco, Mexico, on Monday night.
In another video a resident can be seen diving into the bright waves as bystanders watch on at Puerto Marqués beach.
It is the first time in more than 60 years that the luminous plankton washed up on the beach, the Daily Star reports.
It is speculated that the lack of visitors to the beach due to the coronavirus lockdown has allowed the plankton to thrive.
Acapulco is famous for its nightlife and sun bed-strewn sandy beaches, but people staying at home has seen the beach return to nature.
Pollution from boats might be what normally keeps the plankton away, marine biologists say.
Oaxaca, another city in Mexico, has had crocodiles sunbathing on its beach after the giant reptiles became emboldened by the lack of human activity.
Bioluminescent plankton does not only live in warm climates and has also lit up the waters surrounding the UK in the past.
Photographers flocked to Angelsea in northern Wales last year to capture the ethereal glow.
Bioluminescent bays are the result of a high concentration of plankton which, when they move, cause the waters to light up with a 'glow in the dark' effect.
It's a rare natural phenomenon, as there needs to be a particularly high concentration of plankton. For example, you need thousands just to make one gallon of water light up.
