Etymology: Dactylosurculus: Name from Latin 'dactylus' or Greek 'dactylos' for finger and Latin 'surculus' for sucker of a grapevine tendril. Name refers to the functional analogy with the pseudoclaspers, to the specific shape of the ‘middle’ pseudoclasper; gomoni: Named for Martin Gomon, NMV, Melbourne, Australia,.
Eponymy: Dr Martin Fellows Gomon (d: 1945) is an US/Australian ichthyologist who first went to Australia to Museum Victoria Melbourne (1979) where he is Senior Curator, Ichthyology. [...] (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 15.3 - 18.8, mean 17.5 °C (based on 159 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [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).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

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