Teleostei (teleosts) > Gobiiformes (Gobies) > Gobiidae (Gobies) > Gobiinae
Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); pentherum: Name from Greek 'pentheros' meaning 'of mourning', apparently alluding to the black bar on the pectoral-fin base which, with considerable imagination, could be viewed as analogous to the black arm band worn to signify the death of a close friend or relative in certain cultures..

Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8. This species is distinguished by the following characters: a concave bony interorbital which is less than half pupil-diameter in width; slight or no groove posterodorsal to eye; presence of scales in the midline of the predorsal region; absence of opercular scales; the fifth pelvic ray is branched once dichotomously and more than 80% the length of the fourth ray; adults with the epaxial musculature reaching anteromedially to a point in line with the posterior margin of the eye; elongated spines in first dorsal fin absent (the second spine is longest, reaching to the region of the base of the second dorsal-fin spine); scale pockets are strongly outlined by melanophores and chromatophores; with a dark, vertical bar on the base of the pectoral fin; 6 grey saddles across the dorsum (Ref. 100726).

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=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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).
