actinopterygii

Actinopterygii, or ray-finned fishes, are the largest group of fishes today. They feature fins supported by bony or horny spines ("rays") rather than fleshy lobed fins. This clade includes diverse species like salmon, trout, and seahorses, thriving in both freshwater and marine habitats. Since their appearance in the early Devonian, their adaptable body plans have enabled them to occupy a wide range of ecological niches for millions of years.
