Puriformes

Puriformes is an order of ray-finned fish that includes a diverse range of species, primarily found in marine environments. The order is characterized by its members having a single dorsal fin, which is continuous with the soft rays of the anal fin. This unique feature is a key diagnostic characteristic of Puriformes. The order is further divided into two suborders: Percoidei and Scorpaenopsoidei. Percoidei includes families such as the Perch (Percidae), Rockfish (Sebastidae), and Scorpaenidae, while Scorpaenopsoidei includes the Scorpaenidae, which are known for their venomous spines. Puriformes are known for their varied diets, which range from carnivorous to herbivorous, and their ecological significance in marine ecosystems. They play important roles in nutrient cycling and food webs, and many species are of commercial importance due to their meat and other products.
