Summary:
The Old Wife is easily recognised by its deep compressed body, very tall "spikey" dorsal and anal fins and prominent dark brown to black and white bands.

The derogatory name "Old Wife" reportedly refers to sound made by this species grinding its teeth when caught on hook and line.

Meristic counts: Dorsal fin VIII; I, 14-15; Anal fin III, 14-15; Pectoral fin 13-14; Pelvic fin I, 5; Caudal fin 17; Lateral line scales 55-60.

Body deep, very compressed, oval in shape, head concave with a short pointed snout; dorsal and anal fins high anteriorly, first dorsal distinctly separate from the second; pelvic fins large, prominent.

To 30 cm.

Colour

Body silvery-white to cream, with 6-8 dark brown to black vertical bands of varying widths, the widest and most prominent bands extending from the spinous dorsal-fin to the pelvic fin, and from the tip of the second dorsal fin through the beginning of the soft anal-fin rays respectively. Pale part of fins may be pinkish.
