> Blenniiformes (Blennies) > Dactyloscopidae (Sand stargazers)
Etymology: Myxodagnus: Greek, myxos = mucus + Greek, agnos = pure (Ref. 45335); walkeri: Named after Boyd W. Walker in recognition of his fieldwork which produced much of the present material and many other eastern Pacific dactyloscopids (Ref. 39697).
Eponymy: Professor Dr Boyd Wallace Walker (1917–2001) was an American fisheries biologist; ultimately Professor Emeritus of Zoology-Fisheries at the University of California, Los Angeles, where he worked for over three decades (1949–1980). [...] (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.3 ±0.6 se; based on size and trophs of closest relatives

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