Etymology: Pteragogus: Greek, pteron = wing, fin + Greek, ago = to drive (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated. Tropical
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm TL male/unsexed; (Ref. 9002)
soft rays: 9. It can be distinguished from the other species by its longitudinal lines along the body (Ref. 48636). Differs from P. cryptus and P. guttatus by having IX, 11 rather than X, 9-10 dorsal rays and males with filamentous extensions on first two rather than the first four interspinous dorsal membranes (Ref. 37816).
Western Pacific: Indonesia to the Coral Sea, north to Guam, south to southeastern Australia. Recently recorded from Tonga (Ref. 53797).
Found in various habitats from shallow algae reefs to deep offshore on soft bottom with sponges and hydroid colonies (Ref. 9002). Mostly small, secretive species, usually hiding among dense weeds (Ref. 9002). It rarely leaves its cover except to move quickly between hydrozoan colonies, but not before having a good look around first to make sure its safe (Ref. 48636).

Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01061 (-0.15153 - 0.17274), b=3.03881 (2.95215 - 3.12548), based on LWR estimates for this family-BS (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
