板鳃亚纲 (鲨鱼与 鱼) (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); sherwoodi: In honor of C. W. Sherwood, who discovered the shark washed up on a beach in Canterbury, New Zealand, and presented it to the local museum (See ETYFish).
Eponymy: C W Sherwood discovered the holotype lying washed up on the beach at New Brighton, New Zealand (1920) and presented it to the Canterbury Museum. Nothing further was recorded. (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).
营养阶层 (Ref.
69278): 4.0 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 低的, 最小族群倍增时间4.5 - 14 年 (Fec assumed to be <100).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (52 of 100).
Nutrients (Ref.
