The project is the first known attempt to accurately simulate the structure and functionality of natural living corals, taking into account factors such as water flow around the coral structures, sizes that fit the diversity of fish species and proximity to food (plankton). Coral reefs provide a home for 25 percent of all marine fish species. […]
