World’s biggest underwater cave discovered in Mexico

The world's biggest underwater cave has been discovered by divers in Mexico.

The group connected two underwater caverns to reveal what is thought to be the biggest flooded cave on the planet.

And it is believed that the discovery could help shed light on the ancient Maya civilization, the Daily Mail reports.

Near the beach resort of Tulum, the project found that the cave system known as Sac Actun, once measured at 163 miles, is actually connected with the 53-mile Dos Ojos system.

In a statement, GAM said for that reason, Sac Actun now absorbs Dos Ojos.

GAM director and underwater archaeologist Guillermo de Anda hailed the discovery as an
“amazing” find.

He also said it would help to understand the rich culture of the region, which was dominated by the Maya civilisation before the Spanish conquest.
