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.

Guppy

The guppy is one of the most widely distributed tropical fish, found in freshwater habitats across the Americas. Males display vivid colors and elaborate tail patterns to attract females. They are live-bearers, giving birth to free-swimming fry.
