ANIMAL SPECIES:Soldier, Gymnapistes marmoratus (Cuvier, 1829)
The Soldier occurs mainly in temperate estuarine waters living amongst the seagrass. It is responsible for many stings received by people wading out into shallow waters.
Alternative Name/s
CobblerIdentification
The Soldier has a mottled colouration of brown to dark brown blotches above grading to paler below. The blotches are less distinct in larger fish. The 13 poisonous dorsal fin spines are each separated by incised membrane. There is a large retrorse (backward-pointing) spine on either side of the head below the eye.
The species differs from the similar-looking Fortescue, Centropogon australis by the absence of scales on its body. C. australis does have scaless. The Soldier also has a distinctive protruding lateral line, which is first visible posterior to the opercular margin and terminates on the caudal peduncle.

I just received an email from Dr Hiroyuki Motomura, a world authority on the scorpionfishes. He said, "Tom's image appears for me to be a Bullrout, Notesthes robusta. In overall appearance, coloration and head spine structure, this species is most likely".
"Regarding Sascha's identificaton of Centropogon australis, I have not observed large Centropogon australis, but I doubt whether the species develops the long snout and short spines on the head like the fish in Tom's image".

Thank you Sascha, I stand corrected! I have taken some of your comment and added it to the identification section above.

Hi Tom,
The fish in your photo is a large Centropogon australis, which is commonly known as a Fortescue. Gymnapistes marmoratus (Soldier) differs from the similar C. australis by the absence of scales on its body, which C. australis does posses. The scales are clearly visible in your lovely photo.
G. mamrmoratus also has a distinctive protruding lateral line (see photos on right of page), which is first visible posterior to the opercular margin, and terminates on the caudal peduncle.

Hi Tom, Great photo. Thank you for submitting it. The fish certainly looks like a Soldier to me but I'm not a scorpionfish expert. I will ask an expert to look at your photo. The Soldier is a temperate water fish that is 'officially' recorded only as far north as the Sydney region. What makes your fish particularly interesting is that if it is a Soldier, it was photographed well north of the distribution limit. Thanks again. I'll comment again soon.

Hi I spotted this fish while doing a fish survey at Halifax Park in Nelson Bay, NSW. It looked like a very large Forteque, and I wondered if it might be a Cobbler? Are you able to identify the fish for me from the attached picture? Thanks, Tom Davis, Reef Life Survey Volunteer
