Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 1; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 6; ऐनल सौफट रेज़: 10 - 11. Tooth bands of the premaxillae forming a broad arc of uniform width with squared ends and a shallow notch anteromedially (Ref. 78586). Prevomerine tooth patches separated at the midline and accessory tooth plates narrowing posteriorly to a sharp point along a smooth curve (Ref. 78586). Postcleithral process well developed and projecting sharply posteriad (Ref. 78586). Horizontal eye diameter contained 2.7-3.1 times in head length and interorbital width contained 3.8-7.7 times in head length (Ref. 78586).

Demersal during the day; locally abundant between 10 and 25 m depth zones; migrates closer to shore at dusk to feed on chironomid larvae and ostracods; onset of maturity at rather small size (60-70 mm) and extended reproductive period (Ref. 78586).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00471 - 0.02328), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).
