One fish truly has a unique place in history, particularly because it has managed to exist on earth in some form since prehistoric times. We are referring to the sturgeon, a family of bony fish that is found in North America, Europe, and Asia, with around 27 species.
The sturgeon first appeared in fossil records around 200 million years ago. According to the U.S. Fish and Wildlife Service, the sturgeon predates many fish species, and can survive in many environments, including subtropical to subarctic waters.
