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.
Zebra Danio
The zebrafish is a small cyprinid native to South Asia's freshwater streams. Its distinctive blue-and-gold horizontal stripes and hardy nature make it a popular aquarium fish. It is also the most widely used vertebrate model organism in genetic research.
