Etymology: Gillichthys: Theodore Nicolas Gill (1837-1914) researcher of abyssal fishes and systematics + Greek, ichthys = fish (Ref. 45335).
Eponymy: Professor Theodore Nicholas Gill (1837–1914) was an American ichthyologist, malacologist, mammologist and librarian, a zoologist at George Washington University and associated with the Smithsonian Institution for more than half a century. [...] (Ref. 128868), visit book page.

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing in the genus (Ref. 126274); Occurs at low tide in deep channels produced by the 10 meter tidal amplitude in the Colorado River estuary. Bottom with fine, silty sediments and turbid conditions are prevalent (Ref. 90849).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00353 - 0.02836), b=3.08 (2.84 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (11 of 100).
