Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 11; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 14 - 16; गुदा कांटा: 3; ऐनल सौफट रेज़: 14 - 15; जानवरों की रीड़ का जोड़: 28. This species is distinguished by the following characters: elongate supramaxilla and posterior end of maxilla produced as a thin flexible lamina; a single conspicuous black stripe at inner lining of upper jaw and adjacent membranes; dorsal, anal and caudal fins with narrow, pale (blue in life) distal margins; when alive, dorsal portion of iris golden; lateral-line terminus below verticals between segmented dorsal-fin rays 1 to 4, typically below second to third ray; caudal vertebrae 18 (Ref. 81517).

जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Males of this species are strongly territorial and frequently engage in jaw locking combat, apparently to evict rivals or confiscate their burrows (Ref. 81517). Found in sand/rubble bottoms near reefs in about 5-30 m (Ref 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 28.4 - 29.3, mean 28.8 °C (based on 778 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [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 (Ref. 69278):  3.5   ±0.6 se; based on size and trophs of closest relatives
