Cuisine & Edibility

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.
Great White Shark
The great white shark is the world's largest predatory fish. Found in coastal surface waters of all major oceans, it can detect a single drop of blood in 100 liters of water. Despite its fearsome reputation, attacks on humans are rare.
