Cuisine & Edibility
Arapaima
Large, firm white fillets with a mild, clean flavor and low fat; historically a staple protein in Amazonian communities. Often salted and dried; sustainable harvest is tightly regulated.
Japanese Fugu
Delicate, subtly flavored white flesh with a unique gelatinous texture; poisonous organs contain lethal tetrodotoxin. A Japanese luxury delicacy — preparation requires licensed chefs only.
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.
Japanese Fugu
The Japanese pufferfish, or fugu, contains tetrodotoxin, a poison 1,200 times more deadly than cyanide. Despite this, it is a prized delicacy in Japan, where specially licensed chefs prepare it as sashimi, hot pot, and grilled dishes.
