Yes, it is true, Ireland has its own coral reefs.
They are not as noticeable as tropical coral reefs because
they are in deeper water, and perhaps not as extensive,
but they have a similar structure and richness of marine life.
The coral was first discovered off ireland in 1869 by a
Royal Irish Academy and Royal Dublin Society sponsored cruise.
The inspiration of the Ocean Underworld came from spectacular
fluorescent colours of coral reefs. Often known as "rainforest of the sea".
