Etymology: Plesiops: Greek, plesios = near + Greek, ops = appearance (Ref. 45335); polydactylus: Specific name from the Greek words 'polys' meaning many and 'daktylos' meaning finger, referring to the high number of pectoral fin rays that characterize this species.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 17 - 30 m (Ref. 27772). Tropical
Western Pacific: Naviti Island, Fiji. Recently recorded from Tonga (Ref. 53797).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.6 cm SL male/unsexed; (Ref. 27772)
Specimens collected at an unusually deep site for most Plesiops species, at 17 and 25-30 m (Ref. 27772). Eggs are guarded by the male parent (Ref. 205).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.6 - 27.5, mean 26.2 °C (based on 18 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.5 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 (12 of 100) .
