🔬 What is coral?
Coral might look like rocks or plants, but they're actually tiny animals called polyps. Each polyp builds a limestone skeleton, and over thousands of years, these skeletons accumulate into massive reef structures.

Coral reefs are like underwater cities, hosting thousands of species of fish, sea turtles, sharks, and invertebrates. Every creature plays a role in keeping the ecosystem healthy.
Go deeper🌡️ Threats to reefs
