Migratory Patterns

Silvertip sharks exhibit seasonal migration patterns. They typically start in tropical coral reef areas near islands or continental shelves in the Indo-Pacific region, including countries like Australia, Indonesia, and the Philippines. During cooler months, they move towards deeper offshore waters, sometimes traveling to areas near Japan, Hawaii, and the eastern Pacific coast of Central America. Their migrations are generally linked to changes in water temperature and food availability.
