Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 38 - 48; Anal spines: 0; Anal soft rays: 4. Variable green to brown or grey, depending on habitat (Ref. 48635).

Biology     Glossary (e.g. epibenthic)

Occur in protected coastal shallows over or among algae, seagrasses (Ref. 41878), or floating weeds (Ref. 1602). Juveniles occasionally found near the surface (Ref. 4281). Ovoviviparous (Ref. 205). The males carry the eggs in a brood pouch which is found under the tail (Ref. 205). Used in Chinese medicine to extract Hailong, one of the important drugs (Ref. 12206). Has been reared in captivity (Ref. 35416).

Estimates based on models

Preferred temperature (Ref. 123201): 24.9 - 29.3, mean 28.4 °C (based on 3423 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00037 (0.00016 - 0.00085), b=3.18 (2.99 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.6 se; based on diet studies.
Generation time: 1.3 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming annual Fec<1000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 90.5 [50.9, 169.1] mg/100g; Iron = 0.81 [0.45, 1.52] mg/100g; Protein = 18.3 [17.1, 19.5] %; Omega3 = 0.0989 [, ] g/100g; Selenium = 32.7 [16.8, 72.0] μg/100g; VitaminA = 52.1 [17.5, 149.6] μg/100g; Zinc = 1.4 [0.9, 2.1] mg/100g (wet weight);
