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.

Wahoo

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.
