Etymology: Leptochilichthys: Greek, leptos = thin + Greek, leptos = thin + Greek, cheilos = lip (Ref. 45335).
Eponymy: Alexander Emanuel Rodolphe Agassiz (1835–1910) was born in Switzerland but emigrated to the USA with his eminent palaeontologist father, Louis Agassiz (see next entry), and made a fortune out of copper mining. [...] (Ref. 128868), visit book page.

Estimates based on models
Preferred temperature (Ref.
123201): 2.4 - 2.7, mean 2.5 °C (based on 5 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00163 - 0.00737), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±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.
