Trygonorrhina fasciata
Spot Fiddler Ray in New South Wales and Western Australia in cooler 17-22 °C waters. Learn how to recognise this guitar-shaped ray on Australian seafloors.
Roughly 84 cm from snout to tail, this is a ray that looks like it can't decide whether to be a shark: the body is flattened but elongated, with a distinctly guitar- or fiddle-shaped disc formed by expanded pectoral fins that don't fully fuse at the snout. Look for the bold, contrasting pattern of brown or olive saddle-like bands across a cream or pale background on the dorsal surface, visible even in low-visibility conditions. The long, relatively slender tail sets it apart from the more disc-shaped stingrays, and there are two well-developed dorsal fins near the tail tip. No other common Australian ray combines that fiddle outline with those strongly banded markings.
Fiddler Rays are demersal (bottom-dwelling) and are almost always found resting or cruising slowly across sand, rubble, or seagrass patches, often in very shallow water down to moderate depths. They tend to tolerate a slow, calm approach from divers without bolting, making them relatively easy to observe, though a heavy-handed approach will send them off in a burst of sand. Encounters are typically solitary, and the animal may partly bury itself in the substrate when resting.
Fiddler Rays are ovoviviparous, meaning the eggs develop internally and young are born live, litters are small, which makes each individual ecologically significant in ways that slow-maturing elasmobranchs always are.
Sightings are logged from November through to August, suggesting a broad active season that skips only the coldest late-winter months. This aligns well with the species' cool-water preference of roughly 17 to 22 °C, typical of temperate southern Australian coastal conditions across that period.

Fiddler Rays are an almost exclusively Australian encounter, with the strongest sighting records concentrated in New South Wales and Western Australia, followed by Victoria and South Australia. New South Wales accounts for the largest share of logged sightings, with popular dive areas along the Sydney coast and surrounding region regularly producing encounters. Queensland sightings occur but are far less frequent.
Mapping where Fiddler Ray is logged…
Fiddler Rays are found almost entirely in Australia. New South Wales has the strongest sighting record, with the Sydney region a reliable area to look. Western Australia, Victoria, and South Australia also produce regular encounters, particularly on sandy and mixed-substrate dives in temperate coastal waters.
Logged sightings concentrate between November and August, covering the warmer and mild months of the Australian year. The species favours cooler water around 17 to 22 °C, so the temperate southern coast remains suitable for most of this period. Only the coldest late-winter months show a noticeable dip in sightings.
Look for the distinctive fiddle- or guitar-shaped body outline: a flattened, elongated disc where the pectoral fins don't fully merge at the snout, giving a notched appearance at the front. Bold brown or olive bands across a pale underlay on the back, combined with two dorsal fins near the tail tip, make this species fairly straightforward to identify on a sandy Australian seafloor.
Adults typically reach around 84 cm in total length. They are a medium-sized ray, compact enough to fit on a single camera frame but substantial enough to notice immediately on the seafloor. Females tend to be slightly larger than males, as is common in rays.
No. Fiddler Rays pose no meaningful risk to divers. They lack a venomous tail spine and are not aggressive. A calm approach is rewarded with a close encounter; a clumsy one simply results in the ray swimming away. There is no reason to avoid or interfere with them.
