Etymology: Girardinus: From Charles Girard, assistant of Agassiz (1846-1848).
Eponymy: Dr Charles Frédéric Girard (1822–1895) was a French herpetologist and ichthyologist who was Louis Agassiz’s pupil and assistant at Neuchâtel and who moved with Agassiz to the USA. [...] (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00342 - 0.03356), b=3.08 (2.82 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.3 ±0.16 se; based on food items.

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).
