Acipenseriformes is an order of primitive ray-finned fishes that includes the sturgeons and paddlefishes, as well as some extinct families. Scientific classification or biological classification refers to how biologists group and categorize extinct and living species of organisms. ... Orders See text The Actinopterygii are the ray-finned fish. ... Species See text Sturgeon (Acipenser) is a genus of fishes, of which some twenty different species are known, from European, Asiatic and North American rivers. ... Species Polyodon spathula Psephurus gladius Paddlefishes (family Polyodontidae) are bizarre-looking primitive ray-finned fishes whose snouts are greatly elongated, about 1/2 the length of the rest of the body. ...

Acipenseriform skeletons are largely cartilage. In biology, the skeleton or skeletal system is the biological system providing support in living organisms. ... Cartilage is a type of dense connective tissue. ...
