Summary:
A yellowish-brown to grey stingaree with two large dark blotches on the disc, one forming a "mask" around the eyes and the other centred on the disc. The blotches may be connected by thin medial and lateral lines. Juveniles have black dorsal and caudal fins, fading to grey in adults.

More Info


Distribution

Endemic to Western Australia from Bunbury in the south, to at least Shark Bay, and possibly to the Northwest Shelf, north of Karratha. Inhabits sandy areas and seagrass beds, most commonly offshore in depths to 115 m (possibly to a depth of 178 m).

Features

Disc not especially broad, subcircular, mostly wider than long; broadest part slightly more than eye diameter behind level of spiracles; anterior profile obtuse. Snout fleshy, tip not extended. Eye of moderate size (21-28% preocular snout length). Posterior margin of spiracle mostly angular. Mouth small; 3-4 papillae on floor. Internasal flap skirt-shaped, posterior angle not extended into distinct lobe. Posterolateral border of nostril forming a broad flattened, fleshy lobe. Tail slightly depressed to rounded in cross-section; of moderate length (67-86% disc length); lateral cutaneous folds absent; dorsal fin small; caudal fin lanceolate in young, shorter and broader in adults.

Colour

Ochre to grey above with two large dark blotches, one forming a "mask" around the eyes, the other centred on the disc; blotches may be connected by thin lines along the midline and either side; ventral surface white, becoming darker at fin margins. Juveniles with black dorsal and caudal fins, becoming grey in adults.

Feeding

Feeds mostly on polychaete worms and crustaceans, but also consumes sipunculid worms, molluscs, and echinoderms.

Biology

The species is aplacental viviparous, with females usually producing one young per year (rarely two).
Male disc width (DW) 27 cm; female DW 31 cm.

Fisheries

Although the Masked Stingaree is taken as bycatch commercial trawl fisheries, the species is of no commercial value, and captured individuals are usually returned to the water alive.

Similar Species

Readily distinguished from the sympatric congeners, Striped Stingaree, Trygonoptera ovalis and the Western Shovelnose Stingaree, T. mucosa, by colour pattern, disc shape and dorsal-fin size.

Etymology

The specific name is from the Latin personatus, meaning "masked", in reference to the mask-like appearance of the dark pattern adjacent the eyes.
