Dorsale stekels (totaal) : 0; Anale stekels: 0. Japanese angelshark Squatina japonica has broad pectoral fins with rounded free rear tips, posterior margin nearly straight, inner margin strongly convex; nasal barbels simple and spatulate. Anterior nasal flaps smooth to weakly fringed; dermal folds on sides of head without lobes. Rear tip of inner margin of pelvic fins considerably anterior to origin of first dorsal; very short hypocercal tail. Rows of moderately large spines on midline of back and tail from head to dorsal fins and between fin bases, and on snout and above eyes. Body color blackish brown with small dark and pale spots; no ocelli (eye-like spot) (Ref. 247, 31369, 12951).

A little-known angelshark, found on or near the bottom (Ref. 247). Lives in sandy ground. A carnivore that eats benthic animals (Ref. 9137). Ovoviviparous (Ref. 50449). Utilized for human consumption and for preparation of shagreen (Ref. 247).

Estimates based on models

Preferred temperature (Ref. 115969): 5.7 - 20.7, mean 17.3 (based on 123 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00293 - 0.01558), b=3.07 (2.88 - 3.26), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.5 ±0.37 se; based on food items.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Prijsklasse (Ref. 80766): Medium.
