The Ancient Giants of the Waterways
Sturgeons, often called the "living fossils" of the aquatic world, have been swimming in our rivers and oceans since the time of dinosaurs. These prehistoric fish are known for their enormous size, slow growth, and their most prized product—caviar. However, overfishing, habitat destruction, and the high demand for their roe have placed many sturgeon species on the brink of extinction.

How Long Have Sturgeons Been Around?
✔ Sturgeons date back over 200 million years to the Triassic period.
✔ They have survived mass extinctions, including the one that wiped out the dinosaurs.
✔ Their body structure has barely changed—long, scaleless bodies with bony armor plates.
Unique Traits of Sturgeons
✔ Anadromous fish – They migrate from the ocean to freshwater rivers to spawn.
✔ Slow maturity – Some species take 10 to 20 years to reproduce.
✔ Can live over 100 years – Making them one of the longest-living fish species.
