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.

Summer Flounder

The summer flounder, or fluke, is a flatfish that lies camouflaged on the ocean floor. Born with eyes on both sides, one eye migrates to the left side during development. An ambush predator, it explodes upward to grab passing prey.
