Exploring coral reef ecosystems reveals their zonation into fore reef, reef crest, and back reef, each supporting diverse marine life. Coral polyps, the architects of these habitats, build and maintain the reefs through calcium carbonate secretion. The text delves into the distribution, resilience, symbiosis, threats like bleaching, and the reproduction of corals, which is crucial for reef continuity.

The top layer of a coral reef that is susceptible to wave action and promotes coral growth
The sandy area surrounding a coral reef that may support seagrass beds
Coral reefs are found in warm, clear waters between 30°N and 30°S latitude, with some exceptions in areas like the Persian Gulf
Examples of notable coral reef systems include the Great Barrier Reef, the Mesoamerican Barrier Reef, and the Red Sea reefs
Small animals that secrete calcium carbonate and form the structure of coral reefs
The process of erosion on coral reefs caused by organisms like parrotfish and sea urchins
The diverse shapes and forms of coral species, influenced by environmental factors such as light and water movement
Coral polyps rely on photosynthetic algae called zooxanthellae for nutrients and vibrant colors
When corals are stressed, they may expel their zooxanthellae, leading to coral bleaching and potential death
The ability of coral reefs to recover from environmental stressors is influenced by the tolerance levels of their zooxanthellae
