Etymology: Gogolia: -ia, belonging to: Gogol River, Madang Province, Papua New Guinea, type locality (See ETYFish); filewoodi: In honor of Australian biologist Lionel Winston Filewood (1936-2014), Biologist-In-Charge, Department of Agriculture, Stock and Fisheries, Konedobu, Papua New Guinea, for his work on the poorly known elasmobranch fauna of New Guinea; he intended to describe this shark with Compagno but was unable to do so, whereupon he “generously relinquished” both the task and the holotype to his collaborator (See ETYFish).
Eponymy: Lionel Winston Charles Filewood (d: 1936) is an Australian biologist who worked (1960s-1980s) for the Department of Agriculture, Stock and Fisheries, Papua New Guinea. [...] (Ref. 128868), visit book page.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00180 - 0.01010), b=3.04 (2.84 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 4.2 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Fec=2).
Fishing Vulnerability (Ref.
