The Puerto Princesa Underground River gets a Google Doodle today!

Google celebrates the 7th anniversary of Puerto Princesa Subterranean River National Park as a Ramsar Wetland of International Importance with a special doodle.

The doodle features the entrance of Puerto Princesa's underground river with a boat of travelers entering the world's longest underground waterways at 8.2 kilometers which is also famous for its stalactite and stalagmite formation.

"We are glad to showcase one of the country's most treasured natural wonders through a special Doodle on the Puerto Princesa Underground River," interim Country Manager for Google Philippines Ben King said.

He said it also serves as a nudge to travelers to help conserve the place.

"Aside from celebrating the destination, we hope that this effort serves as a reminder to do our part in conserving it."

In 2012, Ramsar Convention, an international body created for the conservation of the important wetlands, tagged Puerto Princesa Underground River as "unique in the biogeographic region because it connects a range of important ecosystems from the mountain-to-the-sea, including a limestone karst landscape with a complex cave system, mangrove forests, lowland evergreen tropical rainforests, and freshwater swamps.”

A statement released by Google says Puerto Princesa's underground river is a UNESCO World Heritage Site and is one of the New 7 Wonders of Nature. It is also a 24-kilometer stretch of caves that houses 800 endemic plants and animals. It also houses critically-endangered species namely Philippine cockatoo, Hawksbill trutle, green sea turtle and Nordmann's greenshank. — LA, GMA News
