Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Kuhliidae
Etymology: Kuhlia: Because of Heindrich Kuhl, 1797-1821; researcher also with lizards (Gekkonidae).
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; demersal; catadromous (Ref. 51243); depth range ? - 2 m (Ref. 86942). Tropical; 32°N - 28°S
Asia and Oceania: Taiwan, Philippines and Indonesia to islands in the Pacific. The name Kuhlia marginata has been misapplied to other species and therefore some literature records may be suspect (Ref. 41640).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 17.9 cm SL male/unsexed; (Ref. 41640)
soft rays: 11 - 12. Preorbital serrae 18-28; a few fine serrae may be present on suborbital; body depth 2.7-3.05 in SL; orbit diameter 2.75-3.3 in head length; maxilla extending to or slightly beyond a vertical at front edge of pupil; caudal concavity 2.5-3.1 in head length. Silvery, usually with blackish spots posteriorly on dorsal part of body that tends to merge to form bands anteriorly (or the dark pigment is concentrated on scale margins); most of snout and tip of chin blackish; caudal fin pale with a black posterior margin that broadens on lobe tips, then a very broad submarginal pale zone, often preceded by a chevron-shaped blackish band or row of blackish spots parallel with posterior margin; base of caudal fin with small blackish spots; a narrow white margin on soft portion of dorsal and anal fins with a broad blackish submarginal zone anteriorly that narrows posteriorly (broader in dorsal fin than anal) (Ref. 41640).
Primarily a freshwater species; extent of penetration into brackish and marine environments uncertain (Ref. 41640). Has been found in moderately deep (1.5-3 m), rocky, unshaded, flowing water areas of mid-hill rivers (Ref. 6028).
