Biology     Glossary (e.g. epibenthic)

Adults inhabit mangroves and sheltered bays (Ref. 90102). Occur among corals, rocks, and rubble of shallow waters (Ref. 1602, 58302). Benthic (Ref. 58302). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models

Preferred temperature (Ref. 123201): 26.8 - 29.3, mean 28.7 °C (based on 1894 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 199 [102, 425] mg/100g; Iron = 1.03 [0.57, 1.78] mg/100g; Protein = 18.9 [17.8, 20.0] %; Omega3 = 0.145 [0.076, 0.278] g/100g; Selenium = 12.9 [6.1, 27.5] μg/100g; VitaminA = 163 [48, 546] μg/100g; Zinc = 3.23 [2.09, 4.82] mg/100g (wet weight);
