Etymology: Glyphis: Tautonymous with Carcharias glyphis Müller & Henle 1839. (See ETYFish); garricki: In honor of New Zealand ichthyologist John Andrew Frank (Jack) Garrick (1928-2018), for his revisions of the requiem shark family, and “who discovered this species in the form of two newborn males from Papua New Guinea and supplied radiographs, morphometrics, drawings and other details of these specimens (since lost) to the senior author”. (See ETYFish).

Estimates based on models

Preferred temperature (Ref. 115969): 18.3 - 28.8, mean 26.2 (based on 285 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00468 (0.00218 - 0.01003), 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): 4.3 ±0.7 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
