Teleostei (teleosts) > Siluriformes (Catfishes) > Mochokidae (Squeakers or upside-down catfishes) > Mochokinae
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).

Environment: milieu / climate zone / depth range / distribution range Ecology

Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal spines: 3-4; Anal soft rays: 6 - 8; Vertebrae: 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).

Biology     Glossary (e.g. epibenthic)

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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.00700 - 0.03427), b=2.88 (2.70 - 3.06), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
