Animal Species:Red Morwong, Cheilodactylus fuscus (Castelnau, 1879)
The Red Morwong is common in coastal New South Wales waters, where it is seen regularly by divers.
Standard Common Name
The Red Morwong can be recognised by its colouration and extended lower pectoral fin rays. Adults are orange-brown to dark brown above and pale below. Small juveniles are silvery with dark bands crossing the upper sides and dorsal fin.
Adults have large fleshy lips and a forked caudal fin. There are horn-like bumps in front of the eyes.
The Red Morwong occasionally has a banded pattern and looks similar to the Banded Morwong. The lack of bumps on the front of the head in the Banded Morwong can be used to separate the two species.
It grows to 65 cm in length.
The Red Morwong occurs in warm temperate waters of Australia and New Zealand. In Australia it is known from southern Queensland to eastern Victoria. It is common in New South Wales.

Feeding and Diet
Kuiter (2000) states "They (morwongs) feed on worms and small invertebrates which are filtered through the gills from randomly-taken mouthfuls of sand or matter scraped from the rocks".
Other behaviours and adaptations
Red Morwongs are commonly seen resting on the bottom, perched on their long thickened pectoral fin rays.
