Etymology: Apopterygion: Greek, apo = outside + Greek, pterygion = diminutive of pteryx = fin (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; non-migratory; depth range 5 - 80 m (Ref. 75154). Subtropical
Eastern Indian Ocean: northern Tasmania to Port Phillip Bay, Victoria. Endemic to the Bass Strait area in southern Australia.

Morphology | Morphometrics
(total): 16 - 17;
soft rays: 19 - 22. 22-26 pored scales in the anterior lateral line series; 0-13 notched scales in the posterior series. The second dorsal fin without an ocellate black blotch but may be distally blackish, the anal fin pale, occasionally with whitish spots; the pelvic fin pale, and the dorsal fine spines each with two large distal spinules.
Associated with yellow sponges. Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

Estimates based on models
Preferred temperature (Ref. 115969
): 14.6 - 18.3, mean 16.8 °C (based on 120 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00246 - 0.01227), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 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
