Short description आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय सौफट रेज़ (सम्पूर्ण): 10; ऐनल सौफट रेज़: 11 - 13; जानवरों की रीड़ का जोड़: 36 - 37. Creagrutus nigrotaeniatus is distinguished from all its congeners, except C. cracentis and C. maxillaris, by having 8-10 dentary teeth (vs. 4-7) and 4-5 post-anal scales (vs. 1-2). It further differs from most congeners (except C. varii, C. gephyrus, C. cracentis, and C. maxillaris) by having dentigerous surface of the premaxilla longitudinally elongate from ventral view (vs. dentigerous surface triangular). In addition, it can be diagnosed from C. varii by having 8-10 branched rays on anal fin (vs. 15-17) and from C. gephyrus by having 4-5 maxillary teeth (vs. 7-11). It is distinct from C. cracentis and C. maxillaris by having a dark mid-lateral stripe extending from the posterior margin of orbit to the distal tip of middle caudal fin rays (vs. absence of mid-lateral stripe), anterior dentary teeth tricuspid (vs. pentacuspid), and 4-5 maxillary teeth (vs. 8-12) (Ref. 94995).

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=0.01479 (0.00653 - 0.03348), b=2.96 (2.77 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.6 ±0.1 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 (10 of 100).
