Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335); grandiops: The specific name is a latinized combination of the Latin grandis, meaning large or big, and the Greek ops, meaning eye, a reference to the increased size of the eye of this species, particularly in relation to snout length (Ref. 59365).

背棘 (總數) : 2; 背的軟條 (總數) : 7; 臀棘: 3 - 4; 臀鰭軟條: 6 - 8; 脊椎骨: 34. Body is compressed laterally, with a convex predorsal profile, interrupted by a ridge formed by dorsal rim of eye; head somewhat depressed (Ref. 59365). Eye dorsolateral, ovoid, its diameter 64.2-81.0 % of snout length (Ref. 59365). Mandibular teeth 17-26, short and unicuspid, arranged in a single transverse row (Ref. 59365). Maxillary barbel without basal membrane, lacking branches or crenelations, and extending at least to base of pectoral fin; lateral mandibular barbel extending to point just short of anterior margin of pectoral girdle, with 4-5 non-tuberculate branches, lacking secondary branches; medial mandibular barbel 1/2 to 2/3 length of lateral barbel, with 4-5 pairs non-tuberculate branches, lacking secondary branches (Ref. 59365). Dorsal fin spine long, striated, nearly straight, terminating in short, white filament; anterior margin of fin spine with 0-3 small serrations distally; posterior margin with small serrations distally (Ref. 59365). Pectoral fin spine roughly equal in length to dorsal fin spine, striated, slightly curved, terminating in short, white filament; anterior spine margin with many small, antrorse serrations; posterior margin with large, retrorse serrations along entire length (Ref. 59365). Adipose fin short, poorly developed, margin convex (Ref. 59365). Body with large spots, fin spines brown to black (Ref. 59365).
身體側面地是扁長形的, 具有一個被由眼的背部邊緣形成的一個脊中斷的中凸的前背輪廓; 頭部略微扁平的.(參考文獻 59365) 眼背外側的﹐卵形的, 它的直徑 64.2-81.0% 的吻長度.(參考文獻 59365) 下顎齒 17-26, 短與單犬齒的, 排列成橫跨的列.(參考文獻 59365) 沒有基膜，缺乏分支或 crenelations 的上頜骨觸鬚, 而且延伸至少到胸鰭基底; 延伸至點的側面的顎觸鬚正好短的肩帶的前緣, 藉由 4-5 非長有小瘤的分支, 缺乏第二的分支; 中間的顎觸鬚 1/2 到 2/側面觸鬚的 3 長度, 與 4-5 對非長有小瘤的分支, 缺乏第二的分支.(參考文獻 59365) 背鰭棘長的﹐有條紋的﹐和幾乎是直的, 在短又白色的絲狀突起的終端; 末梢部地的具有 0-3個小的鋸齒鰭棘的前緣; 後緣末梢部地有小的鋸齒。 (參考文獻 59365) 胸鰭棘概略長度相等對背鰭棘, 有條紋的, 些微地彎曲, 在短又白色的絲狀突起的終端; 前面的棘邊緣有許多小又向前及向上的鋸齒; 後緣有大的, 逆向的鋸齒沿著整個的長度。 (參考文獻 59365) 脂鰭短, 發展不良的, 邊緣凸狀.(參考文獻 59365) 身體有大的斑點, 鰭棘褐色到黑色.(參考文獻 59365)
Likely inhabits littoral to benthic zones over shell, sand and mud bottoms; no detailed information on diet exists, but species is likely to feed on small gastropods, as do other Synodontis species in Lake Tanganyika (Ref. 59365).
或許居住於到在貝殼，沙與泥底部上的底棲區域的沿海地區。 (參考文獻 59365)
