Species Overview
European Eel
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.
Swordfish
The swordfish is a highly migratory pelagic predator recognized by its long, flat, pointed bill. It can dive to depths exceeding 2,800 meters and possesses a specialized organ that heats its eyes and brain for improved vision in cold, deep water.
