Short description Morphology | Morphometrics

A small species with the following diagnostic characters: acute snout, angle less than 110°, covered to apex with enlarged denticles; disc length 94-101% WD; head length 47-51% WD; preoral length 21-25% WD; distance between nostrils 9-11% WD; distance between first gill slits 20-25% WD; tail moderately compressed above the midbase of the ventral cutaneous fold, width 0.7-0.9 times its height; ventral fold slender, its length 1.1-1.3 times WD, 32-41 times its depth below its midbase; ventral fold depth 1.8-2.4 times tail height at its midbase; distance from cloaca to sting 0.9-1 in precloacal length; 1-3 nuchal thorns, largest pearl-shaped; pectoral fin radials 113-120; monospondylous vertebral centra 35-38 (Ref. 58027).

Biology     Glossary (e.g. epibenthic)

Found most abundant near the coast in regions of high riverine outflow. Largest immature male was found to be 27.5 cm WD. No data on size at birth, with smallest specimen 13.2 cm WD of a late male embryo (Ref. 58027). Data for Max.Length of female from Ref.58027. Caught occasionally by bottom trawl and demersal gillnet fisheries operating off Sumatra and Kalimantan. Utilized for its meat and probably its skin (Ref.58048).
