  Palaeos Vertebrates 100.100  Neopterygii: Neopterygii
Neopterygii means "new wings." Despite this portentious name, the experienced student -- hardened to the bitter disappointments of scientific nomenclature -- will be unsurprised to learn that neopterygians were neither new nor wingèd.
Thus, the changes in the "wings" at the level of the Neopterygii are actually rather mundane and unimpressive.
However, the Neopterygii were able to make more, and more flexible, use of these overlapping plates to expand the oral cavity by interposing an interopercular bone (actually an exapted branchiostegal ray) between the large operculars and the small branchiostegals.

 BioMed Central | Full text | Normal embryonic stages of the Longnose Gar, Lepisosteus osseus
Three features of development are especially noted that compare or contrast with other members of the Neopterygii, and with the Chondrostei.
These are meroblastic cleavage, a well-defined yolk syncytial layer (ysl), and a pit at the posterodorsal edge of the blastoderm, which defines an overhanging dorsal lip.
Lepisosteus is unique among the Neopterygii with respect to this character state.

Conversely, salmons inhabit sea waters and migrate to rivers to breed (anadromous species).
Sturgeons live mainly in coastal waters, but the adults often migrate to rivers and lakes to breed.
The tasty sturgeon flesh has a high commercial value, and the eggs are consumed as caviar.

 Devonian Times - More About Ray-Fin Fishes
Ironically, Palaeoniscum, the fossil that prompted the erection of the taxon "paleoniscoids", is more advanced (or derived) than most of the other fishes traditionally assigned to the "paleoniscoids".
In fact, some authorities consider Palaeoniscum to be an early member of the Neopterygii.
In addition to Palaeoniscum and the Neopterygii, crown ray-fins include the Chondrostei (e.g., Polydon and Acipenser) and the related saurichthids or lizard fishes (e.g., Saurichthys).

They are further grouped into the class Actinopterygii because of their ray fins.
From there they then belong to the subclass Neopterygii, which are the modern ray finned fishes.
They are then further classified into the division of Teleostei, which have refined structure and function of their mouths and fins.

SUBCLASS Neopterygii: modern ray-finned fish: gars, bowfins, "teleosts".
Typically vertebrate except that: cyclostomes have a very primative lymph system which carries some red blood cells.
The lymph system is also incomplete in Dipnoi (lungfish) but fully developed in Neopterygii.

The rest of the actinopterygians, which includes the vast majority of species, are in the subclass Neopterygii: “In their great numbers and degree of anatomical diversity, the modern ray-finned fishes may be considered the most successful of all vertebrates” (Caroll, 1986:136 in Helfman et.
Further, modern teleosts represent the culmination of continuous ‘improvements’ on the basic fish design, within the Neopterygii.
Investigators have traced these changes in the basic fish design with the aid of the fossil record, and have identified important trends in actinopterygian evolution.
