Sturgeons

Sturgeons are some very peculiar type of fish. Sturgeon is actually the common name for the family

Acipenseridae which includes 26 species of fish. Sturgeons are thought to be one of the oldest boned fish in existance and have a habitat range from sub-tropical waters to sub-artic waters and are commonly found in North America, Europe and Asia (Eurasia). Sturgeons have long bodies and are bottom dwellers ranging from 4 to 18 feet long. Like catfish, sturgeons have barbals (the "whiskers") and have something known as scutes rather than scales. Sturgeons are mainly freshwater but have been known to venture out in to saltyer waters. In North America sturgeons can be found in the great lakes, the Mississippi River and even in some parts of Pennsylvania.
