Etymology: Pentaprion: Greek, pente = five + Greek, prion = saw (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; brackish; demersal; depth range 15 - 220 m (Ref. 12260). Tropical; 33°N - 28°S, 47°E - 158°E
Indo-West Pacific: western and southern coasts of India and off Sri Lanka to Indonesia, the Philippines and Ryukyu Islands, and south to the northern part of Australia (Ref. 3131).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm TL male/unsexed; (Ref. 2872); common length : 10.0 cm TL male/unsexed; (Ref. 2872)
Dorsal spines (total): 9 - 10; Dorsal soft rays (total): 14 - 15; Anal spines: 5 - 6; Anal soft rays: 12 - 13. Body is slender, with weakly attached silvery scales. The spines of the dorsal and anal fins longer than the rays; the pectoral fins long and pointed, reaching beyond the anal fin spines; the anal fin is long; the caudal fin lobes rounded.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Inhabits coastal waters. Forms large schools. Probably feeds on small benthic animals. Used for fish meal and duck food.
