Etymology: Mugilogobius: Latin, mugil, -ilis = grey mullet + Latin, gobius = gidgeon (Ref. 45335); filifer: Named for the elongate first dorsal fin present in adult males ('filum' = thread or filament; 'fer' = suffix meaning to bear or carry). More on author: Larson.

Morphology | Morphometrics
soft rays: 7;
Vertebrae: 26. Light brown to grey body with 7 - 9 short oblique dark blotches, bars or chevrons on sides, bars usually broken up into off-set pairs of blotches, anteriormost body marking a dark oblique shoulder bar, head with radiate or reticulate pattern of brown lines, broad brown band crossing branchiostegal membranes on underside of head (Ref. 43716). Second dorsal and anal rays always I,7; longitudinal scales 29-40; TRB 9-13; predorsal scales 13-21, small, reaching close up behind eyes, anteriormost scale somewhat larger than rest; scales on body mostly ctenoid; first spine of dorsal fin usually longest, filamentous (usually white and conspicuous) in adult males (Ref. 43716). Caudal fin rounded (Ref. 43716).
Inhabits mangrove creeks and estuaries, sometimes well into freshwater influence (Ref. 43716).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00444 - 0.02358), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.3 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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
