WhyReef - Fun Facts
Porites corals are one of the biggest corals on Earth, and one of their colonies (or groupings) can grow over 25 feet (8 meters) high. But they grow very, very slowly, only one third of an inch (9mm) a year. So their giant colonies can be up to 1,000 years old! There are 115 different species of porites corals, and their colonies can be flat or finger-like.
