Etymology: Gobiodon: Latin, gobius = gudgeon + Greek, odous = teeth (Ref. 45335); brochus: Named for its modified teeth and associated structures of the lower jaw. More on authors: Harold & Winterbottom.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range - 15 m (Ref. 86942), usually - m (Ref. ). Tropical; 0°C -
Western Central Pacific: Fiji, Great Barrier Reef, New Caledonia and Tonga.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.6 cm SL male/unsexed; (Ref. 36585)
soft rays: 9 - 10;
Vertebrae: 26. Two oblique pigment bars on the head posterodorsal to the eye. Uniquely derived lower jaw, modified anteromedially into a dentigerous, fleshy projection and a row of elongate, transversely oriented papillae in the ventral portion of the cheek. Interopercular-isthmus groove nearly straight. Caudal fin rounded.
Found in association with Acropora loripes and Acropora elseyi; commonly in pairs (Ref. 36585); a coral-commensal species (Ref. 72446). Feeds on copepods, forams, and unidentifiable flocculent material (may represent in part the remains of coral tissue) (Ref. 36585).

Bayesian length-weight: a=0.01023 (0.00475 - 0.02204), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.25 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
