Scientific Details

Meristics.
Dorsal fin spines/rays: XIII, 16-17
Anal fin spines/rays: II, 14-15
Caudal fin rays: 15
Pectoral fin rays: 19-21
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.

Detailed descriptions of fin count and other meristics are in:

Order level detail.
A large and highly diverse group of modern bony fishes many of which have a generalized perch like body form. Most have pelvic fins with one spine and 5 rays and the maxillary bone is excluded from the gape of the mouth. Interrelationships of the group are poorly understood and continue to be studied. They inhabit almost all aquatic habitats from high-altitude strams to the deep sea, although most are marine.

General Description

Body deep, robust, somewhat oval, with a rounded head and a single long-based dorsal fin. Body scales large, bases of dorsal and anal fins with scaly sheath of smaller scales. Colour highly variable, large adults dark greyish to black, or rusty-coloured with a dusky head, pale spots along lateral line and sometimes pale below. Juveniles bright orange with neon-blue lines, spots and a black ocellus ringed with neon-blue on dorsal fin. To 25 cm.

Biology

The Scalyfin is territorial and very bold, especially during the breeding season. They continually graze small algal "gardens" in their home territories and males aggressively protect eggs against all-comers.

Habitat

Coastal rocky reefs and rocky estuaries; juveniles are often found in tide pools, in depths of 3-30 m.

Reefs

Coastal shores
