Summary:

Although named the Eastern Red Scorpionfish, this common species is variable in colour, ranging from bright red to a pale greyish-brown, with darker and lighter blotches and mottling. Juveniles may have a white to purplish blotch across the back of their head. The dorsal-fin spines have a venom gland at the base, and a sting from this species may be excruciatingly painful.

Until recently, this species was called Scorpaena cardinalis, a species that was described from New Zealand. Motomura et al. (2011) showed that S. cardinalis is only found around islands in the Tasman Sea (including Lord Howe and Norfolk islands) and in New Zealand, and does not occur in the waters of mainland Australia.

More Info


Distribution

Endemic to temperate waters of south-eastern Australia from off Caloundra, Queensland, to Beware Reef, Victoria, and possibly further west to Western Port, Victoria. The Eastern Red Scorpionfish commonly inhabits shallow estuaries to deeper offshore reefs in depths to 73 m. It is common on coastal reefs in New South Wales.

The Victorian records are based on few specimens collected respectively in "Victoria" in 1890 and in "Western Port" in 1930; otherwise the species is only known south to Jervis Bay (New South Wales).

Features

Dorsal fin spines/rays XII, 9; Pectoral fin rays 16-18; Gill rakers 4-6 + 10-13 = 14-19; Lateral line scales (pored) 22-24.

Most scorpionfishes are ambush predators and skin flaps and their colour pattern provide excellent camouflage. 

Size

To at least 40 cm.

Feeding

The Eastern Red Scorpionfish is an well-camouflaged ambush predator. It lies motionless on the bottom, moving only when disturbed, and waiting for unwary fishes and crustaceans to come within striking distance of its large mouth. Prey items are swallowed whole.

Biology

The sexes are separate and fertilisation is external. Stewart & Hughes (2010) found that the species breeds during summer and autumn. Females produce hollow, bilobed gelatinous egg masses that provide protection and floatation for the eggs and developing embryos.

Eastern Red Scorpionfish are slow-growing, with individuals reaching 22 cm after 5 years and 26 cm after 10 years. The oldest fish sampled was estimated to be 33 years old. See Stewart & Hughes (2010) for further information on age, growth and reproduction.

Fisheries

Off minor commercial and recreational importance. The species is taken by commercial line fishers and offshore recreational fishers (Steffe et al.1996). The flesh is white and considered excellent eating.

Conservation

  • Stewart & Hughes (2010) suggest that the slow growth rate, substantial longevity, variable recruitment patterns and a highly specialised reproductive strategy may make this species vulnerable to over-exploitation.
  • Remarks

    Motomura et al. (2011) revised the group and determined that Scorpaena jacksoniensis is a valid species, and is what had previously been referred to as Scorpaena cardinalis in eastern Australia. Scorpaena cardinalis is found at Lord Howe Island in the Tasman Sea, northern New Zealand and the Kermadec Islands.

    Similar Species

    Differs from Scorpaena papillosa in usually having a bright red body (vs reddish-brown, to brown or blackish), nine dorsal-fin spines (vs 12), and in growing to a larger size (40 cm vs 20 cm in S. papillosa).

    Etymology

    The species is named after Port Jackson, the type locality.
