Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 21 - 23; गुदा कांटा: 0; ऐनल सौफट रेज़: 25 - 29. Median depression on head. SL/Body Depth ratio = 3.7-3.8. Origin of dorsal fin in same level or slightly behind anal fin origin. Pectoral fins shorter than head and the extremities reach the origin of the pelvic fins. Small eyes with diameter 6.0-6.8 x head length. Affinities: close to M. ussheri, differentiated by the number of dorsal fins and the eyes which are smaller relative to the head length. M. mento also found in the area of repartition and distinguished by the number of dorsal and anal fins and the number of scales on the lateral line.

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=0.01288 (0.00577 - 0.02877), b=2.88 (2.71 - 3.05), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±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.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
