Part 3/10:
Ningaloo Reef, a UNESCO World Heritage Site, hosts a unique ecological event annually, where coral polyps release sperm and eggs during a full moon in March. This spawning coincides with the whale sharks’ migration, leading them to feast on the vibrant coral spawn. The reef boasts an intricate structure; the shallow continental shelf, just a few kilometers from the shore, drops into a deep ocean trench, creating a complex habitat that the whale sharks frequent.
