sturgeon
Ancient roe producer
A sturgeon is a large freshwater fish prized for its roe, which becomes caviar.
Sturgeons are ancient, bony-plated fish found in rivers and coastal waters of the Northern Hemisphere.
They can grow enormous—some species exceed fifteen feet—and live for decades.
Overfishing for caviar has made several species endangered.
