More Info


Endemic to temperate waters of southern Australia, from Inverloch (Victoria), excluding Tasmania. Inhabits coastal reefs in 1-30 metres.

Although only found in small numbers, the Bluelined Leatherjacket is most common on coastal reefs in Western Australia.


Meristic features.
Dorsal fin spines/rays: II; 32-36
Anal fin spines/rays: 31-34
Caudal fin rays: 12
Pectoral fin rays: 12
Vertebrae: 20

Body oblong, moderately deep, very compressed with a small ventral flap and a shallow caudal peduncle. Head large, broadly pointed with small eyes and a very small mouth; teeth large, the central pair in both jaws pointed; a slit-like gill opening mostly above each pectoral fin base. Skin smooth to touch, without spines or bristles on the caudal peduncle; lateral line difficult to detect.

Two dorsal fins; first dorsal-fin spine prominent, situated above the eyes, juveniles with small to moderate-sized barbs along the posterolateral edges, barbs much smaller or obsolete in adults; spine partly received into a shallow groove when folded back; second dorsal fin widely separated from first, with a slightly convex outer margin and not elevated anteriorly; anal fin similar to and opposite the second dorsal fin; caudal fin truncate. Pectoral fins moderately small, rounded. Pelvic fin rudiment small but obvious, immovably attached to rear end of pelvis.


To 35 cm


Sexually dimorphic in colour - males are greenish to yellowish-brown, with bright to pale blue spots, diagonal lines on the head, and horizontal lines on the sides; dorsal and anal fin-rays greenish to orangy-brown, caudal fin membrane orange with bright blue bars near the upper and lower margins, and a bright blue hind margin.

Females are similar on colour, but lack the bright blue hind margin to the caudal fin.

Juveniles are covered in blue spots and have two to three dark brown stripes along the sides.
