Elasmobranchii (sharks and rays) > Carcharhiniformes
(Ground sharks) > Scyliorhinidae
Etymology: Apristurus: Greek, a = without + Greek, pristis = saw + Greek, oura = tail (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal. Deep-water; 24°N - 12°N
Northwest Pacific: known only from the type locality, the South China Sea (possibly off the Chinese coast). Presence in the Western Central Pacific is uncertain (Ref. 11146).

Maturity: Lm ?  range ? - ? cm
Max length : 42.0 cm TL male/unsexed; (Ref. )
Known only from the holotype which was found at 537 m depth. Length is from an immature specimen, might reach at least 50 cm TL. Oviparous (Ref. 50449).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00159 - 0.00631), b=3.12 (2.95 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.8 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Vulnerability (Ref. 59153
): Moderate vulnerability (40 of 100) .
