Etymology: Dawkinsia: Named for Richard Dawkins, for his contribution to the public understanding of science and, in particular, of evolutionary science; exclamatio: The specific name is a reference to the color pattern of this species, which if viewed "snout-down", resembles an exclamation mark; derived from Latin word exclamatio, an interjection, an exclamation.
Eponymy: Dr Clinton Richard Dawkins (d: 1941) is an ethologist and evolutionary biologist who was Professor for Public Understanding of Science (1995–2008) at Oxford, which had awarded both his bachelor’s degree (1962) and his doctorate (1966) and where he [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Adults are distinguished from all other Indian and Sri Lankan Puntius by possessing unique color pattern: a black blotch 2-3 scales wide starting on and above scale 6 or 7 of lateral line series; and another horizontally-elongate, black, tear-shaped blotch about 1 1/2 scales high commencing on lateral line slightly anterior to or above anal-fin origin, on about lateral-line scale row 13 and continuing to caudal fin base (Ref. 55036).

Occurs in clear-water, rock and pebble substrate areas (Ref. 55036). Inhabits both slow-flowing pools and relatively fast-flowing areas (Ref. 55036).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00502 - 0.02287), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.7 ±0.1 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
