背面の脊椎 (合計) : 13 - 16; 背鰭 (合計) : 8 - 11; 肛門の骨: 3; 臀鰭: 6 - 7. Diagnosis: body depth 29.3-31.6% of standard length; interorbital space 17.6-19.0% of head length; 16 dorsal-fin spines; 28 or 29 lateral-line scales (Ref. 53405).

生物学     用語集 (例 epibenthic)

Ovophilic, paternal mouthbrooder (Ref. 12468, 52307). Both parents can take care of the young after hatching (Ref. 12468), but pair-bonding seems relatively weak (Ref. 52307). Maximum TL recorded is 8.65 cm (Ref. 5657).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  高い, １５か月以下の倍増期間の最小個体群 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
