Summary:
A mottled pale grey, pale brownish or yellowish scorpionfish look-a-like, with darker blotches including five along the back, and a large fringed flaps on the anterior nostrils. Although this well-camouflaged sedentary fish mimics scorpionfishes in shape, coloration and behaviour, it lacks venomous spines.

More Info


Distribution

Recorded in Australia from the Shark Bay region, Western Australia, to south of Moreton Bay, Queensland. Elsewhere the species occurs in the tropical, east-Indo-west Pacific. 
This sedentary species inhabits inshore rubble and silty areas in lagoons, brackish estuaries and coastal reefs.

Features

Dorsal fin XIII-XIV, 9-11; Anal fin III, 5; Pectoral fin 12-14; Pelvic fin  I, 5; Lateral line 36-44 tubed scales (+ 4-6 on caudal fin); Gill rakers 3-6 + 12-14; Vertebrae 11-14.
Body moderately deep (greatest body depth 34-39% SL). Head large, 42-44% SL. Posterior rim of anterior nostril with large fringed flap. Opercle with 2 spines, the lower spine strong and conspicuous, the upper spine (near dorsal edge of operculum) weak and concealed by skin and scales; preopercle finely serrate posteriorly, with 3 or 4 large, antrorse (forward pointing) spines on ventral margin. Mouth moderately large and protrusible, reaching to anterior half of eye; supramaxilla present. A band of villiform teeth in each jaw; a chevron-shaped band of villiform teeth on vomer; an elongate patch of villiform teeth on each palatine; no teeth on tongue. Seven branchiostegal rays; branchiostegal membranes not united. Gill rakers short or rudimentary, the first gill arch with 15 to 19 gill rakers. 
Dorsal-fin origin situated over middle of head above posterior edge of preopercle; dorsal-fin membranes project slightly beyond spine tips. Anal fin short based, second anal-fin spine strong and very long (28-32% SL), reaching to or beyond posterior margin of anal fin when depressed. Caudal fin rounded to truncate, with 6 (rarely 5) and 6 branched rays in upper and lower part, respectively, and 4 to 6 unbranched rays in upper and lower part. Pelvic fins positioned behind pectoral fins, the inner ray broadly bound to body by membrane. Pectoral fin with only the upper ray unbranched. 
Scales on body ctenoid, extending onto snout; lateral line relatively low on body, extending from gill opening to caudal-fin base (Gill 1999).

Feeding

An ambush predator that feeds on small fishes, shrimps, and crabs.

Fisheries

Of minor commercial importance in some parts of its range, and occasionally traded in the aquarium industry.
