Scientific Details

Meristics.
Dorsal fin spines/rays: VIII-IX; 15-16
Anal fin spines/rays: 14-15
Caudal fin rays: 11
Pectoral fin rays: 11 + 3
Ventral fin spines/rays: I, 5
Lateral line: 62-65

Interpreting fin count meristics.
Spines are in Roman numerals and soft rays are in Arabic numerals. Spines and rays that are continuous in one fin are separated by a comma. Fin sections are separated by semicolons.

Detailed descriptions of fin count and other meristics are in:

Order level detail.
A diverse group of bottom-dwelling fishes with a bony ridge, or stay across the cheek connecting the bones under the eye with the gill cover. Most species have spines projecting from bony ridges on the head and some have spines projecting from the gill cover. Many species are well-camouflaged ambush predators, often with elaborate cirri, filaments, leaf-like appendages and spiny ridges enhancing their camouflage. Scales are present or absent. Gurnards (also called searobins) have a pair of rostral spines projecting from the snout, large colourful wing-like pectoral fins and crawl over the bottom on their finger-like pelvic-fin rays.

Family level detail.
A large family of bottom-dwelling fishes found mostly on sandy and muddy bottoms, with large bony armoured heads, two bony projections on front of snout, and large, colourful, wing-like pectoral fins. The three lower rays are thickened and free from the rest of the fin, and used for ?walking? over the bottom and probing the substrate for food. They lack venom glands, and display their brightly coloured pectoral fins to startle predators.

General Description

Body slender; head large, bony; snout blunt without projecting spines; scales tiny, those along the dorsal-fin bases large and thorn-like. Reddish to greyish brown above, pale below; fan-like pectoral fins greenish-grey with blue spots, a blue margin and black blotch scattered with white spots near the base. To 50 cm.

Biology

This species is seen more often by anglers than divers. It is commercially fished in southern Australia, and is considered very good eating.
