The eleutheronema tetradactylum is a warm marine fish, has wide salt property, and can live in fresh water, brackish water and seawater environments. Inhabit on the sand bottom or the mud bottom, and enter the shallow water area and the river mouth of the coastal area within 23 m of the water depth and also enter the river downstream river section. Food-borne impurities, mainly feed on benthic organisms. The juvenile fish inhabit at the river mouth and feed on invertebrates such as cladocera, copepods, endpods and isopods; the horns, 50 mm in body length, feed on larval and hairy species of Arthropoda, cephalopoda, shrimps. Adult fish is fed by frightening fish (mainly fishes of Mugilidae and Shishou fish). Widely distributed in the north of the indian ocean and the west of the pacific ocean, from the eastern gulf to the eastern babuyas new guinea and north of australia, to the north to china and japan.
