Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 9; Anale stekels: 1; Anale zachte stralen: 8 - 9. Schismatogobius essi is distinguished by having the following characters: pectoral fin usually with 15 pectoral; pectoral fins with broad black triangular wedge dorsally usually with few rows of dark spots below it; dorsal flns VI-I,9; membrane in flrst dorsal fin posterior to spine 6 not connected to base of spine in second dorsal fln; anal fln I,8-9; ventral surface ofhead, frenum and pelvic disc in male entirely blackish or entirely brownish; and in females, underside of head pale with chin and surrounding area blackish, with diffuse dark brown area on anterior part of branchiostegal membrane and isthmus (Ref. 116768).

Estimates based on models

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

Bayesian length-weight: a=0.00724 (0.00338 - 0.01553), b=3.05 (2.87 - 3.23), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
