There are three distinct oceanic regions
the earth that are home to coral reefs
Major coral reefs are seen as red dots on
this NOAA worldmap. Most of the reefs,
with a few exceptions are found in
tropical and semitropical waters,
between 30 degrees north
and 30 degrees south latitudes.

This outstanding atlas is highly recommended
as the primary resource for more detailed information about coral reefs
worldwide. For more complete and in-depth coverage of the topics
