Elasmobranchii (sharks and rays) > Orectolobiformes (Carpet sharks) > Hemiscylliidae (Bamboo sharks)
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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00398 (0.00177 - 0.00893), b=3.09 (2.89 - 3.29), in cm total length, based on LWR estimates for this Subfamily-BS (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).

Price category (Ref. 80766): Unknown.
