Anal fin spines/rays: III, 8-10
Caudal fin rays: 10-12
Pectoral fin rays: 11
Ventral fin spines/rays: I, 5

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.

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.
Endemic Australian family with a single species.

General Description

Striking red or orange fishes with a compressed body, a large head and large rounded fins; dorsal fin continuous with high rounded lobes; pelvic fins below pectoral fins, both rounded; scales absent, body covered in fine velvety skin. Bright mottled orange, red or brown. Juveniles very pale with red spots. To 46 cm.

Biology

Although relatively common in some areas, the Red Velvetfish is surprisingly well-camouflaged amongst kelp and other macroalgae. These ambush predators feed mostly on crustaceans such as crabs and shrimps. The fin spines are venomous and can inflict an excruciatingly painful sting.

Habitat

Sheltered rocky reefs covered in kelp and other macroalgae, in depths of 1-55 m.
