Etymology: Istigobius: Greek, istios = sail + Latin, gobius = gudgeon (Ref. 45335).
Eponymy: Charles Francis Spence (1907–1982) was a businessman in Mozambique, the type locality, whom Smith thanked for providing personal assistance. Spence later published: The Portuguese Colony of Moçambique: an Economic Survey (1951). (Ref. 128868), visit book page.

Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 7; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 10 - 11; गुदा कांटा: 1; ऐनल सौफट रेज़: 9 - 10; जानवरों की रीड़ का जोड़: 26. Pectoral fin rays entire. Predorsal cycloid scale 7-10, ctenoid on trunk. Few spots on nape; a dusky line running from eye dorsal to sensory pore path, ending at or before pectoral fin base; wavy brown lines on the snout. Pelvic and distal part of anal fins darker in males than in females. Appressed anal fin reaching within a distance of 1-2 scales of caudal fin in male, 2-4 scales in female; appressed 2nd dorsal slightly overlapping caudal in male. Some males exhibit 3-4 vertical bars on abdomen and 2-3 horizontal bars in 1st dorsal fin (Ref. 420); longitudinal scale series 30-32; no scales on cheek and opercle; body depth 4.9-6.1 in SL (Ref. 90102).
Occurs in turbid coastal areas near river mouths at less than 1 m to at least 12 m, Ref. 48637.

Estimates based on models
Preferred temperature (Ref. 123201): 25.7 - 29.3, mean 28.6 °C (based on 2615 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
Nutrients (Ref. 124155): Calcium = 139 [69, 301] mg/100g; Iron = 0.849 [0.417, 1.558] mg/100g; Protein = 18.7 [16.7, 20.3] %; Omega3 = 0.153 [0.067, 0.292] g/100g; Selenium = 16.6 [8.1, 37.8] μg/100g; VitaminA = 145 [39, 485] μg/100g; Zinc = 2.53 [1.67, 3.75] mg/100g (wet weight);
