Short Description
Diagnose after WHITE, KAWAUCHI, CORRIGAN, ROCHEL & NAYLOR, [22508]: A small Myliobatis (attaining about 665 mm DW) with the following combination of characters: dorsal surfaces yellowish brown, usually with variable, irregular dark blotches; tail with a very weak ventral skin fold; stinging spine(s) relatively long (longest spine 10.3–18.6% DW); interorbital space shallowly concave in adult males; anterior margins of pectoral fins moderately convex; cranial fontanelle (visible in dorsal view without dissection) relatively narrow with mostly straight lateral margins; claspers of adult males 6.6–10.2% DW; predorsal length 66.6–78.8% DW; pectoral-fin radials 79–85 (excluding rostral propterygial radials anterior of eyes); total vertebral centra (including synarcual) 115–124; males mature by 429 mm DW.

Biology
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures [733]. Found from the intertidal to the uppermost continental slope. Lives on the sandy areas in the rocky regions of the Japanese and the East China seas [17641]. Also inhabits coral reefs (Ref. 58534). A carnivore feeding on benthic animals [17641].
