A landlocked anchialine pond on Eleuthera Island hosts the highest concentration of lined seahorses on Earth — densities over ten times the global average. Designated Seahorse National Park by the Bahamas National Trust in 2023, it is managed carefully to balance access with conservation; visits are permit-based and numbers are limited. Night snorkels reveal extraordinary behaviour — active hunting, courtship dances, and bioluminescence. A truly rare and scientifically significant encounter, not a casual day trip.
