Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Cepolidae
Etymology: Acanthocepola: Greek, akantha = thorn + Latin, cepulla, cepa = onion. More on authors: Temminck & Schlegel.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; depth range 3 - 50 m (Ref. 90102). Tropical; 37°N - 10°N, 119°E - 141°E (Ref. 56297)
Western Pacific: southern Japan to the China Sea. Also reported from Indonesia and northwestern Australia (Ref. 5978).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 40.0 cm TL male/unsexed; (Ref. 559)
Identified by the spaced series of pupil-sized red spots along upper sides (Ref. 48635).
Inhabits the shallowest water, compared to other cepolids. Lives on muddy substrates, deep as well as in shallow protected estuaries (Ref. 48635). Caught by dredge, but not valued as food fish (Ref. 559, 637).

Estimates based on models
Preferred temperature (Ref. 115969
): 17.2 - 28.6, mean 21.5 °C (based on 66 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00230 - 0.01199), b=2.82 (2.61 - 3.03), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (33 of 100) .
