Have you ever heard about an underwater museum?
A hotel ?
or even a restaurant?
have you ever watched an underwater show?
do you think that there are underwater waterfalls ?
or rivers that run underwater ?
have you ever thought that mermaids may exist ?
are you sure that atlantis never existed ?
90% of oceans is still unmapped .... So, we don't really know ...
Intill today, the underwater world is still a mystery...
