Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 12 - 14; членистые (мягкие) лучи спинного плавника (общее число) : 11 - 14; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 7 - 9; позвонки: 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=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (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.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (K=1.0; assuming Fec<1000).
Fishing Vulnerability (Ref.
59153): Low vulnerability (14 of 100).
