Etymology: Tenuicephalus: Name from Latin 'tenuis' for thin, weak and 'cephalus' for 'head', referring to the delicate and weak nature of the head ossification which often results in damaged specimens when recovered from deep-water trawls.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00167 - 0.00864), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
