Elasmobranchii (sharks and rays) > Carcharhiniformes (Ground sharks) > Pentanchidae (Deepwater catsharks)
Etymology: Apristurus: a-, Latin privative, i.e., without; pristis, from pristes (Gr.), sawyer (but here meaning saw); oura (Gr.), tail, referring to absence of saw-toothed crest of enlarged dermal denticles along upper edge of caudal fin as found in the closely related Pristiurus (=Galeus) (See ETYFish); australis: Latin for southern, referring to its distribution in the southern hemisphere around Australia (See ETYFish).
Eponymy: Pinocchio is a fictional character created by Carlo Collodi in his childrens’ novel: The Adventures of Pinocchio (1883). [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

This species has the following characters: flattened prenarial snout, apparently longer than interorbital width; furrows of upper labial much longer than the lower ones; pectoral fin widely expanding posteriorly, with outer margin a little longer than P1-P2 space; short abdomen, P1-P2 space narrower than preorbital length or anal fin base length; origin of first dorsal-fin just above or slightly anterior to pelvic-fin insertion; 50–64 and 48–68 tooth rows on upper and lower jaws, respectively; teeth with 5 or more cusps, including the anterior ones; egg capsule with no coiled tendrils on anterior and posterior ends, posterior end tapering toward tip; color preserved in alcohol is uniformly pale brownish to light greyish, sometimes light yellowish brown; the dorsal side of body is a little darker than ventral side (Ref. 76943).

Estimates based on models

Preferred temperature (Ref. 123201): 2 - 8.7, mean 6.7 °C (based on 238 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec assumed to be < 10).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (45 of 100).
