Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 3; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 43 - 45; गुदा कांटा: 1; ऐनल सौफट रेज़: 39 - 42. Identified by the long filaments on the dorsal fin of the male (Ref. 48636). Body scaleless above and below lateral line on anterior half (Ref 12934).
Body shape (shape guide): elongated.

Found in coastal reef slopes and deep outer reef lagoons in current channels. Usually in large groups with several large males (Ref. 48636). Inhabits sand-rubble bottoms (Ref. 90102). Found hovering above sandy slopes. Usually forms a harem of one male-phase fish and about a dozen female-phase fish (Ref. 37240). Normally buried when no current is running (Ref. 48636).

Estimates based on models

Preferred temperature (संदर्भ 123201): 24.6 - 28.8, mean 27.4 °C (based on 184 cells).

Phylogenetic diversity index (संदर्भ 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (संदर्भ 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100). 🛈
