What Class designation is given to the White Sturgeon, Acipenser transmontanus?
Answer
Actinopterygii
The Class designation for the White Sturgeon, Acipenser transmontanus, is Actinopterygii. Members of this class are widely recognized as ray-finned fishes. This classification is based on a key morphological characteristic: their fins are supported by bony spines or rays. Although the sturgeon possesses a primitive body structure compared to many other modern bony fishes, its placement in Actinopterygii confirms this fundamental fin structure. This group encompasses the vast majority of extant fish species, setting it apart taxonomically from cartilaginous fishes or other major aquatic vertebrate classes.
