The underwater caves are found around the world. However, their formation and appearance varies according to their environment.
While caves in warmer sea waters are home to coral reefs, the caves in the ice cold waters have less sea life in them.
Underwater caves also known as cenotes (pronounced say-noh-tays) are actually limestone and gypsum sinkholes.
Underwater caves are amazing formations that should be there on every snorkeler and scuba diver's bucket list.
