Scientific Details

Meristics.
Dorsal fin spines/rays: XVIII-XXII, 12-13
Anal fin spines/rays: IV-IX, 3-5
Caudal fin rays: 9
Pectoral fin rays: 8
Ventral fin spines/rays: -
Lateral line: (pores) 8-20

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. Many species have venomous spines.

Family level detail.
Small family of scorpionfish relatives found only in Australia. They have very compressed wedge-shaped bodies, a long-based dorsal fin arising on the snout and attached to the tail fin, and lack pelvic fins and scales. The spines are not venomous.

General Description

Head and body compressed, wedge-shaped, dorsal fin joined to tail fin; lack pelvic fins and scales, and are covered in wart-like bumps. Vary from red to orange, brown to a dirty yellow or white, often with darker blotches. To 22 cm.

Biology

These sedentary fishes regularly shed their skin to prevent the build-up of fouling organisms. The warty skin enhances their camouflage. When disturbed, they often release a cloud of noxious liquid.

Habitat

Rocky reefs and seagrass or algal beds on coastal reefs and in bays and harbours, usually in association with sponges, at depths of 1-45 m.

Reefs

Seagrass meadows

Sponge gardens
