Animal Habitats of the World :Coral Reefs

Coral reefs are highly diverse marine ecosystems formed by colonies of tiny coral animals that build calcium carbonate structures over time. Found mainly in warm, shallow tropical seas, coral reefs support an extraordinary variety of marine life despite covering a very small portion of the ocean floor.Fish, invertebrates, reptiles, and marine mammals rely on coral reefs for food, shelter, and breeding grounds, making them some of the most productive yet fragile habitats on Earth.
