Cuisine & Edibility
Atlantic Sailfish
Firm, mildly flavored flesh similar to marlin; primarily a catch-and-release sport fish. Edible when smoked or grilled but rarely targeted for food; sport anglers typically release it.

Endangered species — consumption is strongly discouraged and illegal in many countries. Historically consumed in parts of Asia; now internationally protected under CITES Appendix II.
Species Overview
Atlantic Sailfish
The sailfish is the fastest fish in the ocean, reaching speeds up to 110 km/h. Its enormous dorsal fin, or 'sail,' can be raised to herd baitfish. When hooked, it performs spectacular tail-walking displays across the water surface.
Whale Shark
The whale shark is the largest living fish species, reaching lengths of up to 18 meters. Despite its enormous size, it is a gentle filter feeder that consumes plankton, fish eggs, and small fish by swimming with its wide mouth open.
