Scoliodon macrorhynchos (Bleeker, 1852), a second species of spadenose shark from the Western Pacific (Carcharhiniformes: Carcharhinidae). pp. 61-76. In P.R. Last, W.T. White, and J.J. Pogonoski (eds). Descriptions of new sharks and rays from Borneo. CSIRO Marine and Atmospheric Research Paper no. 32.
Character: A moderately stout, with head broad, greatly depressed, and trowel shaped shark. Snout bell-shaped in dorsoventral view. Preoral length greater than internarial space and mouth width. Eyes small and without posterior notches. Spiracles absent. Teeth similar in upper and lower jaws. Teeth of anteroposteriors with slender oblique cusps and distal blades but no cusplets or serrations. 25-33/24-34 rows of teeth. Interdorsal ridge absent. First dorsal origin over or behind pectoral rear tips, its midbase much closer to pelvic bases than to pectorals and its free rear tip about over pelvic midbases. Second dorsal fin height 1/3 of 1st height or less. Pectoral fin origin under interspace between 4th and 5th of gill slits. Anal fin much larger than 2nd dorsal fin, with short preanal ridges. Colour light grey, yellowish or brownish grey above, without any colour pattern. 
Habitat: A common tropical and subtropical shark of continental and insular shelves. Viviparous, with an unusual columnar placenta. Fertilized eggs are unusually small, only 1 mm in diameter and with little yolk. Maximum size is about 74 cm. Males maturing at 24-3 
Distribution: Indo-West Pacific including Tanzania, Pakistan, India, Sri Lanka, Malaysia, Singapore, Thailand, Java, Borneo, China, Taiwan, Japan. 
Utility: Caught with hook-and-line, longline, floating and bottom gillnets and set bottom nets, and traps. Utilized fresh for human consumption.

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines : 0; Anal soft rays : 0. Bronze grey above, white below, fins sometimes darker than body; no conspicuous markings (Ref. 9997 ).

Biology     Glossary (e.g. epibenthic)

Found on rocky substrates of coastal waters and lower reaches of tropical rivers (Ref. 244 ). It is uncertain, however, if this species can live in perfectly fresh water for extended periods (Ref. 244 ). Forms large schools (Ref. 244 ). Feeds on small bony fishes, shrimps and cuttlefish (Ref. 244 ). Viviparous (Ref. 50449 ). Common by-catch of the inshore demersal gillnet fisheries, particularly those operating off Kalimantan (Ref.58048). Utilized fresh for human consumption; processed into fishmeal and used as bait for other sharks and bony fishes (Ref. 244 ). Maximum sizes up to 120 cm unconfirmed (Ref. 244 ).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Viviparous, with an unusual columnar placenta (Ref. 244 ). Maternal and foetal placenta comprises the entire placenta (Ref. 39556 ). Transplacental nutrient transfer may be hemotrophic (Ref. 39556 ). Litter size varies from 1 (Ref.58048) to 14 (Ref. 9997 ). Size at birth about 13 to 15 cm TL (Ref. 9997 ). Distinct pairing with embrace (Ref. 205 ).
