A small eel-like reddish-brown pipefish with white dots peppering the body and a short white ‘pug-faced' snout. Adults lack dorsal and pectoral fins, and have a pointed frontal process overhanging the mouth.
These small agile pipefishes easily move around within large plate corals or between the polyps of Galaxea corallites.

Distribution |
Recorded from off North West Cape, Western Australia. Elsewhere the speceis is known to occur in the tropical East-Indo-west Pacific - Indonesia, Western Australia, Palau and Japan. Inhabits coral reefs at 1-20 m, living in association with dendrophyllid corals, including those of the genus Galaxea. |
|
Features |
Dorsal fin absent in adults; Pectoral fin absent in adults; Caudal fin 10; Trunk rings 17; Tail rings 44-46. Body eel-like, slender, slightly compressed; superior trunk and tail ridges continuous; median trunk ridge straight, extending to first tail ring; ventral ridges on midventral line indistinct; all ridges on trunk and tail smooth; rings not distinct. Head pug-nosed; frontal process V-shaped, its dorsal margins denticulate and covered by fleshy skin; mouth inferior with fleshy lips, located below pointed tip of projecting preorbital process; gill opening small, at upper corner of gill cover. Dorsal, anal, and pectoral fins absent; caudal fin small. Brood pouch of male on tail, pouch plates short, pouch type semi-closed. Unlike the bottom-dwelling stage, planktonic specimens have 42 dorsal-fin rays and 10-11 pectoral-fin rays. |
|
Size |
To 7.2 cm TL. |
|
Colour |
Body overall brownish with numerous small white spots and pale principle trunk ridges. The preorbital region and around the mouth are distinctly white and an oval brownish blotch is present on the opercle (gill cover). |
|
Biology |
Males brood the eggs in an enclosed pouch on the underside of the tail. The species has a long pelagic juvenile stage. Non-metamorphosed planktonic stages differ from metamorphosed demersal form in having a dorsal fin, pectoral fins and a tubiform snout. |
|
Conservation |
Bulbonaricus brauni is a listed Marine species under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act 1999 Marine Species). |
|
Remarks |
The planktonic and demersal stages of this species are very different. Planktonic specimens have a typical pointed pipefish snout and dorsal and pectoral fin. During metamorphosis, the fins are lost and the snout shortens markedly. |
|
Similar Species |
Similar to Bulbonaricus davaoensis which has a round spine-like frontal process and lacks marginal spines or denticulations unlike Bulbonaricus brauni with its V-shaped frontal process and spinose or denticulate dorsal margins. |
|
Etymology |
Bulbonaricus is from the Latin, bulbus = bulb and Latin, naricus = nose. The species is named after Mr J. Braun, who collected the holotype. |
