Golden Scorpionfish, Parascorpaena aurita (Rüppell 1838)

More Info


Distribution

Shark Bay region to One Tree Island, Queensland, and at Lord Howe Island in the Tasman Sea, although known only from scattered localities in the Northern Territory. Elsewhere the species is common and widespread in the Indo-West Pacific, from Tanzania east to the Solomon Islands, Taiwan and southern Japan, south to Lord Howe Island, Australia. Inhabits shallow weedy, coral, rocky and rubble areas on reef flats or reefs slopes, usually propping on smaller coral blocks.

Features

Dorsal fin XII, 8-9 (usually 9); Anal fin III, 5; Pectoral fin 16-18 (usually 17); Caudal fin 11-12 (branched rays); scale rows in longitudinal series 35–44; scale rows below lateral line 12–16; scale rows between last dorsal-fin spine base and lateral line 4–7; scale rows between sixth dorsal-fin spine base and lateral line 5–7. 
First and second suborbital ridges well separated, posterior portion of former overlapping anterior portion of latter; first ridge lacking spines, second ridge with two spines behind level of orbit; interorbital ridges well developed posteriorly from middle of eye, joining as a broad loop level with posterior margin of orbit, enclosing a relatively deep depression; occipital pit well developed, fairly deep; larger head and orbit, head length 42.0–48.3% (mean 45.3%) of SL and orbit diameter 11.6–15.2% (12.6%) of SL; longer upper jaw and pectoral fin, upper-jaw length 21.0–26.8% (23.1%) of SL and longest pectoral-fin ray length 28.6–36.5% (34.0%) of SL (Motomura et al. 2009).

Colour

Body strongly variegated, mainly brownish or greyish, suffused with irregular blackish, reddish, yellowish brown and/or white blotches; underside of head white, mottled with brownish or reddish blotches. Spinous portion of dorsal fin strongly variegated, but no distinct black blotches in both sexes. Soft-rayed portion of dorsal fin translucent white, with four poorly defined dark blotches. Lower portion of pectoral fin white, with poorly defined reddish-brown spots. Pelvic fin white basally, reddish-brown or brown distally. Anal fin whitish with three or four reddish-brown bands obliquely across the fin. Caudal fin translucent white, with three brownish or greyish bands; first band at base of fin, second at middle of fin, third at distal margin of fin. (Motomura et al. (2009)

Feeding

Well camouflaged ambush pedator

Similar Species

Parascorpaena aurita lacks a black blotch on spinous portion of the dorsal fin. It differs from other species in the genus Parascorpaena (except P. picta) in lacking a suborbital spine below the eye, and usually having 17 or 18 pectoral-fin rays. The Golden Scorpionfish differs from P. picta in having the first and second suborbital ridges well separated, the posterior portion of the first ridge overlapping with the anterior portion of the second ridge (vs. ridges fused together in P. picta), well developed interorbital ridges forming a broad loop at the rear of the interorbit and enclosing a depression (vs. interorbital ridges weakly or moderately developed and not enclosing a depression in P. picta), a fairly well marked depression at the occiput (depression shallow to moderate in P. picta).
