Etymology: Taeniamia: Name from feminine Latin noun 'taenia' meaning ribbon or band; and feminine Greek noun 'Amia' meaning a fish, often used with cardinalfishes genera. Here as Taeniamia referring to the vertical wide bars and near vertical to curved narrow bars as lines on most of the species in this genus..   More on author: Lachner.

Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 2; Anal soft rays: 14 - 19. Diagnosis: Dorsal rays VII,9; anal rays 11,14-19 (usually 16-18); pectoral rays 14 (rarely 13 or 15). Lateral-line scales 25 + 3-5. Median predorsal scales 5-6 (usually 6). Gill rakers 5-7 + 15-18 (total, 20-24). Body depth 2.3-2.85 in SL, and body width 2.3-2.7 in the depth; eye diameter 2.7-3.1 in head length; first dorsal spine 2.0-2.9 in second spine; second dorsal spine 2.1-2.6, and third dorsal spine 2.2-2.7 in head length; spine of second dorsal fin 2.3-2.6, and second anal spine 2.5-2.9 in head length; pelvic-fin length 4.3-5.3, and caudal-peduncle length 4.9-5.9 in SL. Distance from insertion of pelvic spine to anal-fin origin 4.2-5.5 in SL. Posterior preopercular edge fully serrate or nearly so; serrae on upper part usually minute, rarely absent; ventral preopercular edge serrate on posterior two-thirds. Scaly sheath along anal-fin base well developed (Ref. 54391).

Biology     Glossary (e.g. epibenthic)

Occurs in inshore reefs of bays or lagoons, typically hovering in small groups in the recesses of caves (Ref. 1602, 48635).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.00726 - 0.03306), b=3.06 (2.88 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (12 of 100) .
