The Great Barrier Reef is one of the planet’s largest, most densely inhabited ecosystems. Like any big city, it has distinct neighbourhoods. True reef, lagoon, sand cay, and coastal rainforest. Each community ebbs and flows in response to tides, time of day, and seasons. In this wondrous world that straddles land and water, the four seasons profoundly impact life. Coral City reveals how each season influences the behaviours, feeding patterns, and life cycles of the marine creatures that inhabit the region.
