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.
シイラ
The mahi-mahi, also known as dorado or dolphinfish, is among the most colorful pelagic fish in the ocean. Its iridescent blue, green, and gold body fades rapidly after death. It is a fast-growing species, rarely living beyond five years.
