The three main types of coral reefs are fringing, barrier, and atoll. Schools of colorful pennantfish, pyramid, and milletseed butterflyfish live on an atoll reef in the Northwestern Hawaiian Islands.
t is sad to know that not all corals, you can find on the same country. You need to travel to find them. I wonder if blue corals can be found elsewhere?
Blue Coral live only in the Indo-Pacific in the tropics of the Indian and Pacific oceans and they are unusual in that they are blue in color, they have a blue skeleton all other corals just about have white skeletons and also in that they haven’t changed in their form for over 60-70 million years.
