A sturgeon is a very large fish that lives in rivers and seas in the colder parts of the northern world — Russia, the Caspian Sea, parts of Europe and North America. It looks ancient, because it is: sturgeon have hardly changed for many millions of years. Instead of ordinary scales, the body carries rows of bony plates, the snout is long and pointed, and the mouth points downward for feeding along the bottom. Some kinds grow longer than a person is tall and live for decades.
