大小 / 重量 / 年齡
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5608)
背棘 (總數) : 12 - 14; 背的軟條 (總數) : 11 - 14; 臀棘: 3; 臀鰭軟條: 7 - 9; 脊椎骨: 30 - 32. Body slightly elongated, highest at origin of dorsal fin; dorsal profile gently rounded, ventral profile rather straight (Ref. 35977). Mouth very low; jaws usually equal; maxillary may or may not extend to a vertical line through anterior margin of eye (Ref. 35977). All teeth on both jaws conical, recurved, arranged in outer and inner series (Ref. 35977). First dorsal spine very short, all spines with a lappet near tip; all dorsal fin soft rays usually branched (Ref. 35977). First anal spine very short, length of subsequent spines increasing progressively, and all spines with a small lappet near tip (Ref. 35977). Pectoral fin reaching between anus and third anal fin spine (Ref. 35977). Pelvic fin filamentous, reaching between anus and second anal fin spine (Ref. 35977). Scales ctenoid on lateral surface of body (Ref. 35977).
Occurs over sand bottoms near rocks where they feed on invertebrates. Forms schools. Bury themselves in the sand to evade predators (Ref. 6770).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [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).
營養階層 (Ref.
69278): 3.5 ±0.37 se; based on food items.
Generation time: 1.1 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (K=1.0; assuming Fec<1000).
Fishing Vulnerability (Ref.
59153): Low vulnerability (14 of 100).
