Elasmobranchii (sharks and rays) >
Carcharhiniformes (Ground sharks) >
Scyliorhinidae (Cat sharks)
Etymology: Apristurus: Greek, a = without + Greek, pristis = saw + Greek, oura = tail (Ref. 45335).
Environment / Climate / Range
Ecology
Marine; bathydemersal; depth range ? - 1041 m (Ref. 58018). Deep-water, preferred ?; 16°N - 10°N
Eastern Indian Ocean: known only from the type locality, the Andaman Sea. Reported from India (Ref. 45255).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 26.0 cm TL male/unsexed; (Ref. 244)
Known only from the holotype. Maximum length presumably comes from an immature specimen. Oviparous (Ref. 50449). Not utilized at present.
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): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00157 - 0.00666), b=3.11 (2.93 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.7 ±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): Low to moderate vulnerability (28 of 100) .
