Great Hammerhead Sharks Found Staying Year-Round in Bahamas

New research reveals that prey abundance and habitat quality in the Bahamas are keeping some critically endangered great hammerhead sharks from migrating.

• Scientists have confirmed that some great hammerhead sharks are remaining in the Bahamas year-round instead of undertaking their usual seasonal migrations.
• The behavior is attributed to the abundance of prey, access to cool deep waters, and the protection provided by the Bahamas' marine reserves.
• Great hammerhead shark populations have declined by over 80% in the last three generations, with the species classified as critically endangered by the IUCN.
• Tracking and dietary studies suggest that individual differences in diet may influence whether sharks stay in the Bahamas or migrate to other regions, such as the U.S. East Coast.
• The Bahamas, particularly around Andros Island, provide crucial habitats for these sharks, highlighting the importance of marine conservation in the region.
