Etymology: Devario: Bangla/Bengali:‘debari’, local name for these fishes; also meaning ‘brother in law’ (Ref. 2031);  coxi: The specific name refers to the type locality area (Cox's Bazar), but could also refer to the gene fragment used to identify the species (cytochrome c oxidase subunit 1, often shortened to COXI); or to Hiram. A noun in the genitive case. Cox (1760±1799), after whom Cox's Bazar was named..

簡短描述 型態特徵 | 形態測量圖

Devario coxi is similar to D. aequipinnatus in color pattern, with distinct P+1, P and P stripes along the side, but P and P-1 stipes confluent anteriorly and containing light spots (vs. integer to close to pectoral girdle, and interstripe I integer except occasional interruption anteriorly). It differs from D. aequipinnatus by the combination of having more branched dorsal- fin rays (11½±12½ vs. 9½±10½, exceptionally 11½), more circumpeduncular scales (14, vs. 12, rarely 14); slightly deeper body (body depth 29.9±33.2 vs. 26.7±30.8% SL), and shorter upper jaw (upper jaw length 8.3±9.3 vs. 9.2±12.0% (SL). It is distinguished further from striped species of Devario in southern and south-western India, D. fraseri, D. malabaricus, D. mysoricus, and D. neilgherriensis by having infraorbital process vs. absent (Ref. 116720).

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=0.00891 (0.00371 - 0.02139), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.0   ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
