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.

Whale Shark

The whale shark is the largest living fish species, reaching lengths of up to 18 meters. Despite its enormous size, it is a gentle filter feeder that consumes plankton, fish eggs, and small fish by swimming with its wide mouth open.
