Editing Threadfin (section)

==Description==
Their bodies are [[Ichthyology terms#E|elongated]] and [[Ichthyology terms#F|fusiform]], with [[Ichthyology terms#S|spinous]] and soft [[dorsal fin]]s widely separated. Their tail fins are large and deeply forked, indicating speed and agility. The mouth is large and [[Ichthyology terms#I|inferior]]; a blunt snout projects far ahead. The jaws and palate possess bands of [[Ichthyology terms#V|villiform]] (fibrous) teeth. Their most distinguishing feature is their [[Fish anatomy#Fins|pectoral fins]]: they are composed of two distinct sections, the lower of which consists of three to seven long, thread-like independent rays. ''Polynemus'' species may have up to 15 of these modified rays.

In some species, such as the royal threadfin (''[[Pentanemus quinquarius]]''), the thread-like rays may extend well past the tail fin. This feature explains both the common name threadfin and the family name Polynemidae, from the [[Greek language|Greek]] ''poly'' meaning "many" and ''nema'' meaning "filament." Similar species, such as the [[mullet (fish)|mullets]] (family [[Mugilidae]]) and [[milkfish]] (family [[Chanidae]]), can be easily distinguished from threadfins by their lack of filamentous [[Fish anatomy#Fins|pectoral rays]].
