How old is the oldest coral reef?
480 million years old
The southern third of Isle La Motte contains remnants of the Chazy Reef, which, at 480 million years old, is considered the oldest reef in the world where corals first appeared.

Individual polyps are linked by tissues to form colonies.[1] – Reef structure is developed when polyps secrete calcium carbonate into the sea. Here’s a look at some of the interesting facts about the ecosystem. Coral reefs are made by thousands of tiny organisms called polyps.[2] – Coral reefs are one of the world’s most colorful and diverse ecosystems, and though they cover only about 1 percent of the ocean floor, they have a huge effect on the health of the rest of the world. Healthy coral reefs mean healthy oceans which means healthy planet.[3]
