Eponymy: Nathaniel Thayer Jr (1808–1883) was an American philanthropist and financier. [...] James Erwin Böhlke (1930–1982) and his wife Eugenia Louisa Böhlke née Brandt (1929–2001) were both ichthyologists who worked at the Academy of Natural Sciences of Philadelphia, where he was Curator of Ichthyology (1954–1982).

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=0.01148 (0.00540 - 0.02440), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.41 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Fec=1,000).

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

Price category (Ref. 80766): Unknown.
