Etymology: Dawkinsia: Named for Richard Dawkins, for his contribution to the public understanding of science and, in particular, of evolutionary science.
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 [...] Sir William Thomas Denison (1804–1871) became Lieutenant Governor of Van Diemen’s Land (Tasmania) (1846) and Governor-General of New South Wales, Van Diemen’s Land, Victoria, South Australia, and Western Australia (1854).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00898 - 0.01221), b=3.02 (2.98 - 3.06), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  2.6   ±0.1 se; based on size and trophs of closest relatives
Generation time: 1.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
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).
