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); freycineti: In honor of French Navy officer Louis de Freycinet (1779-1841), commander of the expedition during which holotype was collected. (See ETYFish).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0. Caudal fin with a pronounced subterminal notch but without a ventral lobe (Ref. 13575). Black spot behind gills small, not in the form of a conspicuous ocellus (Ref. 13575).

A little-known bottom shark, probably common on coral reefs (Ref. 247); tide pools and sea grass beds in 0-12 m (Ref. 90102). Oviparous (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 115969): 27.9 - 29.1, mean 28.6 (based on 14 cells).

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

Bayesian length-weight: a=0.00407 (0.00181 - 0.00918), 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): 3.4 ±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 (49 of 100).

Price category (Ref. 80766): Unknown.
