Tarpon
Bony flesh with a strong, somewhat coarse texture; rarely eaten in modern sport fishing. Primarily catch-and-release; not commonly consumed due to bones and Vulnerable status.
Species Overview
Arapaima
The arapaima is one of the largest freshwater fish in the world, reaching up to 4.5 meters. An obligate air-breather, it must surface every 10-20 minutes to gulp air. Its tongue is bony and used to crush prey against the roof of its mouth.
Tarpon
The tarpon is often called the 'Silver King' for its large mirror-like scales and acrobatic leaps. This ancient species has existed for over 100 million years and can breathe air using a modified swim bladder.
