European sea sturgeon

The European sturgeon is a critically endangered fish that once thrived along Europe’s coasts. It migrates between the sea and rivers to breed, a rare behaviour among fish. Its populations have drastically declined, making it a symbol of conservation efforts.

• It breeds in rivers but lives most of its life in the sea.
• Once common across Europe, it is now critically endangered.
• It is often confused with the Baltic sturgeon, a different species.
