The Mud Flathead is pale with dark mottling and its eyes have long, branched iris lappets.
In the past, this species has been called Suggrundus jugosus and Insidiator jugosus. A review of the family (Platycephalidae) by Imamura placed this species in the genus Ambiserrula.
The Mud Flathead has a pale body with variable brown, black or dusky mottling on the body and fins. The sides of the head and lower jaw are often banded.
The eyes have long, branched iris lappets. Many other species of flatheads such as the Crocodile Fish, Tasselsnout Flathead, and Fringe-eye Flathead also have iris lappets.
The Mud Flathead inhabits muddy estuaries. It is usually buried in the substrate during the day and feeds at night.
This species is endemic to Australia. It is known from the central coast of Queensland to central New South Wales.
