Physical Appearance
The sturgeon is a comparatively basal species of fish, which date back to the Cretaceous period. Scientists believe it is a transitional species of cartilaginous fish and bony fish, and is also regarded as a kind of Ganoidei with cartilage. The fish is marked by multiple blocks of osteons.
Specimens can range between 200 to 500 cm (79 to 200 in) in body length, and weigh 200 to 500 kg (440 to 1,100 lb) on average. A grown-up sturgeon measures up to 4 metres (13 ft) long, and weighs over 450 kg (990 lb), ranking the third biggest only to the White sturgeon and Atlantic sturgeon. Its head is acuminate, with the mouth under its jaw.
