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.

Greater Amberjack

The greater amberjack is the largest of the jacks, known for brutal head-shaking fights and powerful dives toward structure. Found near reefs, wrecks, and offshore platforms in tropical and subtropical waters worldwide.
