In the ocean, schools of fish move as if a single organism. This is due to the coordinated instinctive reactions of each individual. Relatively simple mathematical models can be used to simulate this. In northern Taiwan, I chose several artificial reefs to photograph fish schools. Artificial reefs change local currents, forming vortices that stir sedimentary nutrients from the bottom. Plankton multiply, attracting higher-level consumers, and forming new food chains. Schools of chicken grunt, attracted by rich food sources, became the subjects of this series of photos.
