Etymology: Cottus: Greek, kottos = a fish (Ref. 45335).
Eponymy: Lyman Belding (1829–1917) was a professional bird collector who wrote a series of articles about his trips, such as: Collecting in the Cape Region of Lower California, West (1877) and A Part of my Experience in Collecting (1900). [...] (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=0.00589 (0.00281 - 0.01234), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

Generation time: 3.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Fec=181).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).
