Species Overview

Pirarucu

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.

Thazard-bâtard

The wahoo is one of the fastest fish in the ocean, capable of reaching speeds of 97 km/h. Its elongated, torpedo-shaped body and razor-sharp teeth make it an efficient pelagic predator found in tropical and subtropical waters worldwide.
