Migratory Patterns

Grey Reef Sharks exhibit limited migratory patterns. They typically remain within a specific reef area throughout the year, showing strong site fidelity. However, some individuals may undertake short-distance movements between neighboring reefs or along coastlines. These movements are usually within the same general region, such as around islands in the Indo-Pacific or along the Great Barrier Reef in Australia. Grey Reef Sharks do not undertake long-distance migrations across oceans or between countries.
