South China Sea Coral Reef Food Web
Coral Reef
South China Sea — Philippines, Vietnam, Malaysia, China
Description
The South China Sea contains thousands of coral reefs on atolls, shoals, and island fringes supporting extraordinary Indo-Pacific marine biodiversity. Reef fish assemblages include over 3,300 species, and the reefs serve as spawning aggregation sites for commercially important groupers and snappers. Blast fishing and cyanide poisoning have degraded many of these food webs.

Key Interactions
- Bumphead parrotfish form schools that bioerode coral and shape reef morphology
- Grouper spawning aggregations attract predators and provide fishing targets
- Tiger sharks patrol reef edges and control turtle and ray populations
- Blast fishing destroys three-dimensional reef structure, collapsing habitat complexity
