Teleostei (teleosts) > Siluriformes (Catfishes) > Trichomycteridae (Pencil or parasitic catfishes) > Trichomycterinae
Etymology: Trichomycterus: Greek, thrix = hair + Greek, mykter, -eros = nose (Ref. 45335).
Eponymy: Colonel M A Chilton was the military attaché of the American Embassy in Santiago de Chile. He accompanied Eigenmann on his tour of the ‘Switzerland of Chile’ (i.e., Chilean Lake District, southern Chile). (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00400 - 0.02388), b=3.04 (2.84 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming Fec < 100).

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