Etymology: Hemiscyllium: hemi-, from hemisys (Gr.), half, presumably referring to similarity and/ or close affinity to Scyllium (=Scyliorhinus, now in Scyliorhinidae) and/or Chiloscyllium; skylion, Greek for dogfish or small shark (See ETYFish); hallstromi: In honor of philanthropist Edward Hallstrom (1886-1970), trustee and chairman of Taronga Zoological Park (Sydney, Australia), where holotype and paratype were alive in captivity (See ETYFish).
Eponymy: Sir Edward John Lees Hallstrom (1886–1970) was born in Coonamble, New South Wales, Australia. [...] (Ref. 128868), visit book page.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00398 (0.00176 - 0.00901), b=3.09 (2.89 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.3 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): Moderate to high vulnerability (51 of 100).
