Polydactylus is a genus of threadfin that mainly are native to the Indian, Atlantic and Pacific Oceans, especially in coastal or brackish waters (such as mangrove or estuaries).[2][3] Some may even enter rivers and a single, P. macrophthalmus, is a freshwater fish from rivers in Borneo.[3]

Most species do not surpass 72 cm (2.4 ft) in standard length, but two can reach up to 1.7–2 m (5.6–6.6 ft).[3]
