Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 8 - 9; Anale stekels: 1; Anale zachte stralen: 8 - 9. Diagnosis: Eleotris pellegrini is distinguished by second and fourth suborbital free neuromast rows on cheek extending ventrally past horizontal row 'd' ('2,4' pattern), row 'os' not connected with row 'oi' at ventro-posterior margin of operculum ('open' pattern); 15 pectoral fin rays; no teeth on vomer; scales in zigzag series 10-12, and 18-24 in transverse forward series (Ref. 123271). Within the pattern '2.4' group, Eleotris pellegrini differs from E. acanthopoma in having 15 pectoral fin rays vs. 16-17 and 28-34 scales in predorsal series vs. 30-42; it differs from E. vomerodentata by the absence of teeth in the vomer vs. presence; it differs from E. sahanaensis by a greater head length, 31-37% of standard length vs. 30-32%, and more scales in zigzag series, 10-12 vs. 10 (Ref. 123271).

This species is supposed to be mainly amphidromous (Ref. 123271). Maximum size up to 64 mm standard length (Ref. 123271). Epibenthic in fresh and brackish waters (Ref. 6802); it lives in the lower part of rivers, in muddy to clear rivers with sandy to gravel bottom between 5 to 10 m in altitude (Ref. 123271). It is carnivorous (Ref. 123271).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00391 - 0.02676), b=3.02 (2.79 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.8 ±0.3 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
