Freshwater Moray, Gymnothorax polyuranodon (Bleeker, 1853)
The Freshwater Moray can be recognised by its colour. It's distribution in Australia is restricted to a number of streams in far northern Queensland.
The Freshwater Moray can be recognised by its colour and habitat. It is yellowish to brown with dark spots on the head, body and fins. The snout and lower jaw of adults are pale. The species is often wrongly identified as a species of Uropterygius because it appears to lack a dorsal fin. A fleshy dorsal fin, which originates behind the gill openings, is present.
It occurs in estuaries and lower reaches of freshwater streams.
It occurs in the tropical Western Pacific. In Australia it is only known from a few creeks on the eastern coast of the lower Cape York peninsula, Queensland.
