Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; demersal; depth range 5 - 20 m (Ref. 90102). Subtropical
Western Pacific: known only from southern Japan, Taiwan, and Philippines.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 2.3 cm SL male/unsexed; (Ref. 40821)
Dorsal spines (total): 19 - 20; Dorsal soft rays (total): 4 - 5; Anal spines: 7 - 8; Anal soft rays: 4 - 5. Acanthoplesiops species with the following autapomorphic character states: 1) anterior two thirds of belly naked and 2) first two (instead of only the 1st) pterygiophores of dorsal-fin spines inserted between 2nd and 3rd neural spines.
Cryptic and rarely seen (Ref. 90102). Eggs are guarded by the male parent (Ref. 205).

Estimates based on models
Preferred temperature (Ref.
123201): 21.6 - 29.1, mean 28.5 °C (based on 499 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00175 - 0.01195), b=3.11 (2.88 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-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.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
