Species Overview

Betta

The Siamese fighting fish is famous for its vibrant colors and flowing fins, developed through centuries of selective breeding. Males are highly territorial and will flare their gill covers at rivals. They possess a labyrinth organ for breathing atmospheric air.

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.
