Etymology: Pristiophorus: pristio-, presumably derived from prio (Gr.), to saw, but treated here as a noun (a saw); phorus, from phoreus (Gr.), bearer or carrier, referring to saw-like snout (note also that pristis is Greek for sawfish) (See ETYFish); japonicus: -icus (L.), belonging to: Japan, where type locality (not specified) is situated (See ETYFish).

Краткое описание определительные ключи | морфология | морфометрия
Pristiophorus japonicus has a long, narrow, and narrowly tapering rostrum (rostrum length is 26-29% of TL), distance from rostral tip to barbels about equal or slightly greater than distance from barbels to mouth (1:1.1-1.2); distance from rostral barbels to nostrils about equal to distance from nostrils to 1st gill slits. About 15-26 large rostral teeth on each side of the rostrum in front of the barbels, 9-17+ behind them; distance from mouth to nostrils 1.1-1.2 times internarial space. Tooth rows 34-58 in upper jaw. Dorsal and pectoral fins covered with denticles in large specimens. Lateral trunk denticles largely unicuspidate. First dorsal fin origin behind free rear tips of pectorals by eye length or more (Ref. 247).
Caudal fin almost straight, with slender upper and lower lobes; pectoral well developed but are not ray-like (Ref. 6871).
Lives on continental shelves and upper slopes on or near the bottom. Also found in coastal waters on sand or mud bottoms. Feeds on small bottom organisms using its barbels to poke the bottom with its snout. Ovoviviparous, with 12 young in a litter.

Estimates based on models
Preferred temperature (Ref. 123201): 7.7 - 21.8, mean 17.4 °C (based on 199 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.8 ±0.58 se; based on food items.
устойчивость к внешним воздействиям (Ref. 120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Fec=12).
Fishing Vulnerability (Ref. 59153): Very high vulnerability (82 of 100).
