Summary:
A brown to greenish-brown medium-sized whipray often with many small, faint white spots and flecks, and a uniformly white underside, sometimes with a dusky margin. Juveniles lack the white spots and may have dark spots near the rear of the disc, and a dark tail with bands beyond the sting. 
This species was previously known as Himantura toshi.

More Info


Distribution

From Darwin, Northern Territory, to the Clarence River, New South Wales. Elsewhere the species occurs in southern Papua New Guinea.
Inhabits shallow coastal sandy and muddy areas in estuaries and mangrove flats. 

Features

Tail long, whip-like, without skin folds; base of tail circular in cross-section, not depressed; disc broad and rhombic; snout relatively short and broadly triangular; denticle band on disc well developed in adults; tail with 1-2 venomous spines.

Feeding

Feeds mostly on prawns and crabs, and also consumes small bony fishes.

Biology

The species is aplacental viviparous, with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures.
Males mature at ~50 cm DW (disc width), and the young are born at ~14 cm DW.

Fisheries

May be taken as bycatch in commercial trawls.

Similar Species

This species has been confused with the closely related Blackspotted Whipray, Maculabatis astra. Most early records of M. toshi are based on misidentified M. astra
The Blackspotted Whipray is densely covered in small black spots surrounded by smaller pale spots or rings, and has alternating pale and dark saddles on the tail beyond the caudal spine in juveniles.
