توصيف مختصر
ريخت شناسي | ريخت ستجي بوسيله انداره گيري
شعاع نرم باله پشتي (کل): 85-93; شعاع نرم باله مخرجي: 75 - 88; مهره ها: 48 - 51. Body robust, highest near base of pectoral fin, completely covered with oval, ca.1.5 mm, cycloid scales. Anterior segment of lateral line extending close to dorsal margin of body and from above anus along midline of body. Head profile convex, cheek and gill-cover scaled, while rest of head naked. Mouth slightly oblique with posterior margin of maxillary vertically expanded ending well behind eye. Anterior nostril closer to upper lip than to posterior nostril, both with low rim. Small opercular spine strong and pointed, almostcompletely covered by skin, and not reaching posterior margin of opercle (a few specimens with spine reaching just beyond hind margin of opercle). Ventral margin of preopercle with four distinct spines and one spine on preopercular crest (spine often covered by skin; one specimen with two spines on crest).
Origin of dorsal fin above tip of pectoral fin, anal fin origin just behind midpoint of fish (some specimens with preanal up to 59 % SL). Pectoral fin placed on mid-body level with peduncle higher than long. A distinct spine on cleithrum just above base of pectoral fin (one specimen with spine ending in a blunt tip). Anterior gill arch with 2–3 (2–4) plate-like rakers on upper branch, one long raker in the angle between the two branches and lower branch with 4–5 long rakers, followed by seven (6–9) plate-like rakers. Longest gill filament
slightly shorter than longest raker. Two minute pseudobranchial filaments (Ref. 80456).
Bellottia robusta differs from its congeners by the following combination of characters: depth at origin of anal fin 17.5–23.0 % SL, small teeth blunt or pointed, four spines on hind margin and one on crest of preopercle, distinct spine on cleithrum above base of pectoral fin, anterior gill arch with 5–6 long rakers, predorsal 44.0–49.5 % SL and precaudal vertebrae 12 (Ref. 80456).

50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
جهندگی (Ref.
120179): زياد, كمينه زمان لازم براي دو برابر شدن جمعيت ، كمتر از 15 ماه (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
