More Info


Distribution

Endemic to eastern Australia from southern Queensland, to about Twofold Bay, southern New South Wales. Occurs mostly on inshore sandy areas and on the inner continental shelf in depths to about 100 m.

Features

Disc suboval, slightly longer than wide; snout short & broadly rounded; ridges of sharp thorn-like denticles on shoulders and midline of disc; tail 1.3-1.4 times longer than disc in adults; dorsal fins large, widely-spaced.

Size

Grows to about 120 cm TL, although individuals rarely exceed 110 cm.

Colour

Brownish with or without blotches, and an ornate pattern of lilac bands (with darker margins) including a distinctive triangular or diamond-shaped marking just behind the eyes; underside whitish.

Feeding

Carnivore - feeds mostly on crabs and shrimps.

Biology

Fiddler rays have internal fertilisation and are aplacental viviparous (ovoviviparous) - meaning that the embryos develop inside eggs and hatch within the uterus of the mother before birth. Females produce litters of 2-3 pups, which are born at a length of about 25 cm TL.

Fisheries

Taken as bycatch in commercial trawls, and marketed as guitarfish.

Conservation

IUCN: Least Concern

Remarks


Similar Species

The similar Southern Fiddler Ray, Trygonorrhina dumerilii, lacks the  triangular marking on the head behind the eyes.
