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.
Channel Catfish
The channel catfish is the most abundant and widely fished catfish species in North America. It has a keen sense of smell, with taste buds distributed across its entire body, enabling it to locate food in murky water.
