In addition to being a food resource for more than 500 million people, a habitat for 25% of marine biodiversity, coastal protection in more than 100 countries and an economic resource of nearly $36 billion per year, corals have many other surprising features:
- The coral colony does not age, it constantly regenerates
- For a large number of species, reproduction takes place once or twice a year depending on the moon and water temperature
- The Great Barrier Reef is the only animal formation visible from space: it extends over more than 2300 km
- Corals produce powerful chemicals able to fight several diseases such as cancer, arthritis, bacterial infections, Alzheimer’s disease, heart disease and other viruses
- Corals and humans have a common genetic heritage
- Corals are at the origin of the fine sand of tropical beaches
- Fluorescence is a strange and mysterious phenomenon whose true function is still not well known
- Without corals to protect coasts, waves could be twice higher
For these reasons it is vital to protect them. Help us by adopting a coral!
