Etymology: Zenarchopterus: Particle zen, derived from zao = to give life + Greek, archos = anus + Greek, pteron = fin. More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; depth range 0 - ? m. Tropical
Indo-West Pacific: India, Malay Peninsula, East Indies, Philippines, Hainan Island in China, Taiwan, New Guinea and northern Australia (Ref. 10943). Known from the lower Mekong (Ref. 12693).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 10 - ? cm
Max length : 23.0 cm TL male/unsexed; (Ref. 7050)
soft rays: 10 - 13. This species is distinguished by the following characters: upper jaw distinctly wider than long; width divided by length 1.05-1.35; sixth anal fin ray of adult males much thickened and enlarged, not reaching base of caudal fin; fourth to seventh dorsal rays of adult males slightly elongate; a prominent dark brown stripe along the midline of the snout.
Found at the surface levels in coastal waters, estuaries and rivers. Feeds on terrestrial insects. Not seen in markets (Ref. 12693).
