Etymology: Scylliogaleus: Etymology not explained, presumably a combination of Scyllium and galeus, i.e., a “galeid” shark with “nostrils as in Scyllium” (=Scyliorhinus, Scyliorhinidae). (See ETYFish); quecketti: In honor of London-born conchologist John Frederick Whitlie Quekett (1849-1913), Curator, Durban Museum (South Africa), who provided holotype [Boulenger consistently misspelled Quekett’s name as “Queckett”]. (See ETYFish).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00240 (0.00110 - 0.00521), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.5 se; based on diet studies.

लौटाव (Ref. 120179): बहुत नीचे, न्यूनतम जनसंख्या दुगनी समय अवलागत 14 महीने। (Fec=2).

Fishing Vulnerability (Ref. 59153): High vulnerability (61 of 100).

Price category (Ref. 80766): High.
