📖 Overview

Found in shallow water on continental and insular shelves . Enters estuaries . Feeds mainly on small teleost fishes but also takes crustaceans and cephalopods . Viviparous , with 6 to 25 pups in a litter . Has a remarkable wing-shaped head which is nearly or quite half of its body length, the function of which is uncertain, maybe for maneuvering or for increasing the surface area of some of the sense organs . Probably harmless to people . Caught commonly, but in low numbers, by inshore gillnet fisheries. Particularly common in catches off Kalimantan. Probably a common fisheries species where it occurs . Meat utilized for human consumption; liver is a source of vitamin oil . Offal probably utilized for fishmeal . Reported to reach 300 cm TL .
