Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 22 - 30; Raggi anali molli: 4.
Adults inhabit coral reefs (Ref. 9710). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Males may be brooding at 5.0-5.5 cm SL (Ref. 5316). Also found in lagoons and seaward reefs (Ref 90102).
Life cycle and mating behavior
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
Monogamous mating is observed as both obligate and genetic (Ref. 52884). Male carries the eggs in a brood pouch (Ref. 205).

Estimates based on models
Preferred temperature (Ref.
123201): 25.2 - 29.3, mean 28.4 °C (based on 3103 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5002 [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): 3.8 ±0.50 se; based on food items.
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 151 [86, 315] mg/100g; Iron = 0.997 [0.526, 1.827] mg/100g; Protein = 18 [17, 19] %; Omega3 = 0.131 [0.070, 0.249] g/100g; Selenium = 33.1 [15.3, 80.8] μg/100g; VitaminA = 91.3 [28.7, 282.2] μg/100g; Zinc = 1.89 [1.21, 2.82] mg/100g (wet weight);
