Species Overview

European Sturgeon

The European sturgeon is a critically endangered anadromous fish that can live over 100 years. Once abundant in European rivers, it is now restricted to a small population in the Gironde estuary. Its eggs are harvested as beluga-grade caviar.

The neon tetra is one of the most popular freshwater aquarium fish, known for its iridescent blue and red horizontal stripes. Native to blackwater streams of the Amazon basin, it thrives in schools of six or more.
