Etymology: Holohalaelurus: holos (Gr.), whole or entire, i.e., being a form of Halaeurus without any labial folds or grooves in the mouth (See ETYFish); grennian: From the old English grennian, grin, referring to its wide, broadly arched mouth and relatively large dentition, which resembles an “ominous grin” (See ETYFish).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 4.0 ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
