Elasmobranchii (sharks and rays) >
Squaliformes (Sleeper and dogfish sharks) >
Somniosidae (Sleeper sharks)
Etymology: Scymnodalatias: scymno-, referring to previous placement in Scymnodon; dalatias, referring to lack of dorsal spines like most sharks in the family Dalatiidae (sometimes included within Somniosidae) (See ETYFish); garricki: In honor of J.A.F. (Jack) Garrick (1928-2018), New Zealand shark biologist, who proposed Scymnodalatias in 1956 [senior author’s name also seen as Kukuyev] (See ETYFish).
Eponymy: Dr John Andrew Frank (Jack) Garrick (1928–2018) was a New Zealand ichthyologist with a specialization in elasmobranchs. [...] (Ref. 128868), visit book page.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00164 - 0.00880), b=3.14 (2.95 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.1 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref.
59153): High vulnerability (58 of 100).
