Banded Bellowsfish, Centriscops humerosus (Richardson 1846)

More Info


Distribution

Circumglobal in temperate waters of the southern hemisphere, including southern Australia, New Zealand, South America and South Africa; adults benthic or benthopelagic, juveniles pelagic on the continental shelf and slope at 350–1000 m (300–700 m in Australian waters).

Features

Meristic counts: Dorsal fin VI–VII, 16-19; Anal fin 17–21; Pectoral fin 16–18; Pelvic fin I, 5; Caudal fin 9.

Head and body: Body very deep, almost circular, highly compressed, depth 38–62% SL; upper and lower body profiles asymmetrical; nape of small specimens with an angular hump and a pronounced rounded hump in adults; snout long, tubular, length 26–33% SL; upper edge of orbits strongly serrated in large specimens; nape with angular hump at small sizes and pronounced rounded hump in large adults,

Fins: Dorsal‑fin spines set into a dorsoposteriorly skewed hump, 2nd dorsal fin enlarged,  40–47% SL; pelvic fins small.

Scales: Four well-developed bony plates present at the shoulder region, bristle-like spines absent. Scales modified into coarse denticles, covering almost all of head and body.

Size

To 28 cm SL

Colour

Whitish with up to 5 oblique dark-edged orange bands, bands uniformly orange in very large adults; dorsal, anal and caudal fins with dusky to orange hue distally; juveniles bluish grey with colourless fins, bands absent.

Feeding

Carnivores, feeding on benthic invertebrates including crustaceans, bryozoans, polychaetes, pteropod molluscs and occasionally fish such as the lanternfish Lampanyctodes hectoris.

Biology

Oviparous (eggs hatch and develop outside the body) with planktonic eggs and larvae.

Fisheries

Commonly discarded as by-catch in commercial trawl fisheries and in the scalefish trap sector of the gillnet, hook and trap fishery. Frequently taken near 600 m with commercial catches of Ling, Gemfish and King Dory.

Conservation

Not evaluated.

Remarks

Juveniles have smaller eyes, a smaller hump on the nape and a very different colour pattern from adults. Until recently, juveniles and adults were thought to be separate species.

Etymology

Centriscus is from the Latin centrum, meaning point, prickle, spur, in reference to the large second dorsal-fin spine. They are commonly called Bellowsfish, as their shape resembles an old fire bellows.
