Reefs are underwater formations primarily composed of corals and other marine organisms.
They are incredibly diverse and colorful habitats that host a wide variety of marine life, such as tropical fish, mollusks, and algae.
Reefs are important not only for their beauty but also for their ecological function. They act as natural barriers that protect coastlines from erosion caused by waves and storms.
Additionally, they play a crucial role in the health of oceans, serving as homes and food sources for numerous species. However, reefs are threatened by pollution, climate change, and destructive fishing, making their conservation essential.
