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.
Atlantic Bluefin Tuna
The Atlantic bluefin tuna is one of the largest bony fish, capable of crossing the Atlantic in under 60 days. A single specimen has sold for over $3 million at Tokyo's fish market. It can maintain a body temperature above the surrounding water.
