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.
Tarpon argenté
The tarpon is often called the 'Silver King' for its large mirror-like scales and acrobatic leaps. This ancient species has existed for over 100 million years and can breathe air using a modified swim bladder.
