Cheilodactylus fuscus
Red Morwong patrol rocky reefs along New South Wales and Queensland. Learn how to spot and identify this Australian endemic underwater.
A solid-bodied fish around 45 cm long, the red morwong has a warm reddish-brown to brick-red colouration on the upper body fading to a paler belly, with a distinctively blunt, fleshy-lipped snout typical of the morwong family. Its pectoral fins are large and paddle-like, often used to prop the fish upright on rocky substrate. Look for the relatively uniform body colour and the rounded head profile to separate it from patterned relatives.
Red morwong are typically seen resting or moving slowly close to rocky reef, using their broad pectoral fins to steady themselves against the substrate. They tend to hold their ground rather than bolt when approached, making steady, calm approaches by divers more productive than rushing. Being carnivores, they can often be found hunting along reef edges and sandy patches adjacent to rock.
Like other morwongs, the red morwong has thick, fleshy lips adapted for picking invertebrates off hard surfaces, a feeding strategy that keeps it tightly associated with rocky reef habitats rather than open water.
There is not yet enough sighting data to point to a specific peak season, so treat it as a year-round resident. Its observed temperature niche of roughly 18 to 24°C aligns with temperate to subtropical conditions along the New South Wales and southern Queensland coast throughout the year.
Reef neighbours a diver could mistake it for. Use the identification notes above to tell them apart.
All recorded sites for this species sit within Australia, with the strongest model-predicted presence spread across New South Wales and Queensland. Rocky reef and sandstone wall diving along the New South Wales coastline offers the best chance of an encounter, with Queensland sites extending the range northward.
Mapping where Red Morwong is logged…
Red morwong are an Australian species, with records concentrated in New South Wales and Queensland. Rocky reef sites along the New South Wales coast are your best starting point, where the temperate water temperatures match this fish's preferred range.
Current sighting data does not show a clear seasonal peak, so they are considered a year-round possibility along the Australian east coast. Their comfortable temperature range of 18 to 24°C is present in New South Wales and Queensland waters through most of the year.
Look for a stocky, 45 cm fish with a reddish-brown upper body, paler belly, blunt fleshy lips, and large paddle-like pectoral fins. The relatively uniform warm reddish colouration and rounded snout are the quickest field marks on the reef.
Red morwong typically reach around 45 cm in length. They are a solidly built fish, so at that size they have a noticeable presence on the reef without being the largest fish in the water.
No. Red morwong pose no threat to divers. They are generally calm and approachable on the reef, and a slow, non-threatening approach is all that is needed for a close look.
