Etymology: Danio: From ‘dhani’, local Bengali/Bangla name for small minnows (Ref. 2031);  dangila: 'dangila' is presumably a Bengali local name, but it lacks a proper reference (J. Müller, pers. comm., April 2021).  More on author: Hamilton.

簡短描述 型態特徵 | 形態測量圖

背的軟條 (總數): 11-12; 臀鰭軟條: 15 - 19; 脊椎骨: 34 - 38. Danio dangila can be distinguished from all congeners except D. assamila, D. catenatus, D. concatenatus, and D. sysphigmatus by produced first ray in pectoral and pelvic fins, large cleithral spot, and pattern of dark rings enclosing light interspaces on the side. It differs from those species by having vertically extended cleithral spot (vs. round in all other species), absence of complete anterior interstripe Ia (vs. present in D. assamila and D. concatenatus), round rings in series along side, width of dark perimeter of about same width as diameter of light centre (vs. elongate in D. assamila and D. sysphigmatus, with narrower perimeter in D. sysphigmatus), ring pattern usually extending onto caudal peduncle (present on part of caudal peduncle in D. catenatus and D. concatenatus, absent in D. assamila and D. sysphigmatus), and 32-34 lateral line scales (vs. 35-38 in D. sysphigmatus) (Ref. 101154).

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00370 - 0.02149), 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.).
