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.

ヨーロッパウナギ

The European eel undertakes one of nature's most remarkable migrations, traveling 5,000 km from European rivers to the Sargasso Sea to spawn and die. Despite centuries of study, its breeding grounds were only recently confirmed.
