Sturgeon: The Living Fossil of Aquatic Ecosystems and the Legend of “Black Gold”
Sturgeons (scientific name: Acipenseriformes) are among the oldest extant bony fish on Earth, originating in the Mesozoic Era around 200 million years ago. They witnessed the rise and fall of the dinosaurs and are often hailed as “living fossils of the water.” Renowned for their distinctive body shapes, long lifespans, and prized caviar, sturgeons also serve as flagship species in freshwater ecosystems and play a crucial role in studies of biological evolution.
