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.

Mero

The goliath grouper is the largest grouper in the Atlantic Ocean. This massive reef dweller can swallow prey whole and produces a distinctive booming sound by contracting its swim bladder to ward off intruders.
