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.
Perca-gigante
The barramundi is a large, catadromous predator native to the Indo-West Pacific. It is a protandrous hermaphrodite, beginning life as male and transitioning to female after several years. Highly prized in both sport fishing and aquaculture.
